Abstract
Okullardaki eğitim-öğretim çalışmalarının sağlıklı yürütülememesinin en büyük sebebi sınıf yönetiminin günümüz çağına uyarlanıp verilememesidir. Öğretmen-öğrenci iletişimi bozulmasından dolayı etkili öğrenme ortamı birçok nedenden dolayı sürdürülemez durumdadır. Bu nedenler : Sınıfların kalabalık olması, on iki yıllık zorunlu eğitimin kişiler tarafından kabul edilememesi, sınava dayalı sistemin zorunlu olması, okuldaki etkinliklerin az olması, gibi nedenlerden dolayı eğitim-öğretim durma noktasına gelmiştir. Sınıfta öğrenme ortamının sağlanması için öğrencideki öğrenme motivasyonu seçici hale getirilmelidir. Ancak böyle yapılırsa, öğrencinin sınıf düzenini bozmasına, konuşmasına, gereksiz hareketlerine engel olunabilecektir. Bunun sonucunda sağlıklı bir sınıf yönetimi ortaya çıkacaktır. Bu zamana kadar öğrencinin sınıf içi düzenli düzensiz hareketlerini tespit edip, aynı anda öğrenci velisine GSM üzerinden haber veren bir sistem bulunmamaktadır. SUS ilk defa tasarlanıp geliştirilen, sınıf yönetiminde öğrenci davranış bozukluklarını aynı anda veli ile koordinasyona geçerek ortadan kaldırıp, dersi daha iyi dinlemesini sağlayarak, öğretmeni edilgen olmaktan çıkarıp etkin sınıf ortamına sokan dünyada ilk defa uygulanacak yeni teknolojik eğitim materyalidir.The biggest reason why educational activities in schools cannot be carried out properly is that classroom management cannot be adapted to today's age. An effective learning environment is unsustainable for many reasons due to the deterioration of teacher-student communication. These reasons: Education has come to a halt due to reasons such as crowded classes, twelve-year compulsory education not being accepted by people, the examination-based system being mandatory, and the lack of activities at school. In order to provide a learning environment in the classroom, the student's learning motivation should be made selective. However, if this is done, the student will be prevented from disrupting the classroom order, talking, or making unnecessary movements. As a result, a healthy classroom management will emerge. Until now, there is no system that detects the student's regular and irregular movements in the classroom and simultaneously notifies the student's parents via GSM. SUS is a new technological educational material that has been designed and developed for the first time in the world and will be applied for the first time in the world, eliminating student behavioral disorders in classroom management by coordinating with the parents, enabling the teacher to listen to the lesson better, and putting the teacher into an active classroom environment.

TARFNAME GSM, BLUETHOOT VE WlFl-SMS MODÜLLÜ KONTROL BASLIGI Teknik Alan Sinif yönetimindeki aksakliklardan dolayi yasanan disiplin sorunlari, egitim- ögretiminin basarili olmamasina neden olan engellerin en büyügüdür Hizla gelisen teknolojinin yanlis kullanilmasindan dolayi toplumun sosyal ve kültürel degerleri hizla yozlasmaktadir. Bunun sonuncunda ergenlik çaginda bulunan ortaokul ögrencilerini sinif içinde disiplini bozacak kimliklere sokmaktadir. Okullarda sinif yönetimini, disiplini saglamaya yönelik birçok madde siralanir. Onlardan bazilari; etkinlestirilmis egitim ve ögretim ortami, etkinlestirilmis rehberlik sistemi, etkinlestirilmis veli-okul isbirligi, okul binasinin sosyal-kültürel faaliyetler içinde kullanilmasi, yapici okul disiplin kurallarinin islemesi gibi. Fakat uygulamaya gelince maalesef hepsi kâgitlarda yazili kalir ve bu nedenle ögrenciler üzerinde etkisi olamamaktadir. Bulus, Dünya üzerinde ilk defa bir sinif içinde ögretmen-ögrenci iletisimi ile ilgili, egitim-ögretim alaninda tüm problemleri, ayni anda ögrenci velisi ile koordinasyon saglayarak ortadan kaldiran yeni teknolojik bir cihazdir. Yazilimi, teknolojik tasarimi ile özgün olan etkili bir uygulama alanina sahip çok yönlü teknoloji yönü agir basan, kullanilmasi basit hem bluetooth, hem de GSM üzerinden tek sim kartla Wi-Fi SMS programi çalisan bir elektronik sistem agi ile ilgilidir. Önceki Teknik Klausmeier'e (1992) göre ögretmen, siniftaki grubun lideri olarak mevcut atmosferi kontrol altinda tutma durumunda olan kisidir. Disiplin kültürünün olusmadigi okullarda ögretmenler, egitim ögretime odaklanmak yerine isyankâr ruhlu ve asiri hareketli ögrencilerin olusturduklari disiplin sorunlariyla ugrasmak zorunda kaldiklari, Edwars'a (1997, Akt. Celep, 2004) göre ise ögrenciler genelde su durumlar karsisinda disiplin sorunu çikarabilirler: Ögrencilerin kendilerini anlamsiz ögrenme ortami içinde bulmalari ve bagimsiz düsünmeyi ögrenme konusunda kendilerine yardim edecek birilerinin olmamasi durumunda sorun çikarabilirler. Ögrencilerin sevmedigi derslerle ilgili alistirmalar yaptirildiginda ve cezalandirma ön planda tutuldugunda disiplin sorunlari ortaya çikarabilecegi gibi bulusla iliskileri fikirleri bulunmaktadir fakat bulus dünya üzerinde ilk defa gelistirilip uygulandigi için yalnizca bulusu destekleyen görüsler vardir, önceki teknik bulunmamaktadir. Bulusun Amaçlari Bulusumuz yukarida tespit edilen olumsuzluklari ortadan kaldirmak üzere gelistirilmis kullanisli olmasinin yani sira kolay tasinabilir boyut ve agirlikta GSM, bluethoot ve Wifi-SMS modüllü kontrol basligidir. Bulus dünyada ilk defa ögrencinin anlik kontrolünü ögretmenin yani sira velinin ögretmen ve ögrenci ile senkronize ve es zamanli olarak ögrencinin sinif içindeki durumunu tespit etmesine imkan saglamaktadir. Siniflarda olusan ve bir türlü önüne geçilemeyen disiplin problemlerini, gelistirdigimiz yeni teknolojik alet SUS ile sinif yönetimini bozan olumsuz davranislarin önüne farkli bir metotla geçilebilecegini gösterip, MEB müfredatina uygun hale getirip yayginlasmasini saglamaktir. Egitim-ögretim süreci okullarda sinif içinde yasanan disiplin problemlerinden dolayi aksama hatta durma noktasina geldigi için yeni teknolojik materyaller, yeni olusumlar önem arz etmektedir. Ülkenin gelecegi ile dogrudan ilgilidir.

Daha sonra kapasitif mikrofonu iced aparatin uç kismina yerlestirilerek, hassas kablolara zarar gelmemesi için aparat etrafini izole bant ile sarilmistir. Kontrol kumandasi ve devrenin yerlestirecegi kutular router yardimiyla kullanisli hafif sekle getirilmistir. Bulusun her asamasi özgün olabilmesi için, hazir kulaklik kullanmak yerine farkli parçalarin birlesimi sonucunda kontrol basliginin tasarimi düsünülerek prototipe eklenmistir. 4 tane led ve bir tane lityum pil ünitesi bulunmaktadir. Lityum pil ünitesi bir tane 3.7 voltluk pil ile çalisir konumdadir. Samsung sarj aletiyle sarj edilebilir bir girisi ile birlikte ekstra lityum pil ünitesi üzerinde de Bus Converter bulunmaktadir. Bus Converter 3.7 voltu 5 volta yükselten bir converter ayni zamanda pilin sarj olmasini da saglamaktadir. Bus Converter'dan alinan 7 volt Mic Preamp Modülü'ne verilmektedir. Preamp mikrofondan yolladigimiz ses sinyallerini üzerinde bulunan bir Opamp entegresi sayesinde çogaltir, yükseltir daha sonra bize voltaj degeri olarak verir. Yani kisik sesle konustugumuzda 1-2 volt gibi yüksek sesle konustugumuzda 4- volta çikabilir. Bunun amaci da bize konustugumuz ses sinyalinin siddetine göre kirmizi ledimizin parlamasini ayarlar. Kisik sesle konusursak kirmizi led daha az(sönük) , yüksek sesle konusursak daha çok(yüksek) isikli yanar. Daha sonra Preamp Modülüne Step Up Converter'dan gelen voltaj girdikten sonra PNP Trasistör kullandik. Iki tane transistör kullandik. Bir tanesi kirmizi ledi tetikliyor konusma siddetimize göre isigin parlakligi azalip artiyor digeri de Buzzer'i tetikliyor. Buzzer da ses siddetimize göre ses çikartiyor yüksek seste yüksek geri dönüs sinyal sesi alçak seste daha kisik bir ses sinyali çikariyor. Bununla birlikte kirmizi ledden ayri olarak üç tane daha ledimiz var. Bunlar: sari, mavi yesil. Bu ledler de ses sisteminden tamamen bagimsiz olarak çalisiyor. Kutunun üzerinde 3 tane buton yerlestirdik ledlerin renkleriyle es olacak sekilde. Bus Converter'dan aldigimiz 7 voltluk voltaji araya 620 ohm'luk bir direnç koyarak akimin düsmesini sagladik (ledlerin çalisma voltajina göre). 620 ohm'luk direnç akim sinirlandirma görevi gördü. Bütün butonlarimizin birer ucuna paralel olarak "+" giris ile girildi. Daha sonra butonlarin diger arti uçlarini da her bir ledin arti girislerine verdik. Ledlerin eksi uçlarini da birlestirip voltaji 7 volta yükselten Bus Modülünün eksi ucuna verdik ve böylece devre tamamlanmis olundu. 3 tane butonumuz var yesil sari ve mavi ledlerle ayni renklerde. Bu kumanda üzerindeki dügmelerin hangisine basarsak ses sinyalinden bagimsiz olarak ilgili buton ilgili ledi yakma görevine sahip. GSM Modüllü Kontrol Basligi için; GSM modülü için ARDUINO'dan d10 ve d11 pinlerindeki girisleri GSM Modülündeki RX ve TX pinlerine baglidir. Devre boyunca kullanilan eksiler ortak oldugu için GSM modülündeki eksi ile ARDUINO'daki eksi kabloyu birlestirip ana eksi gidisine baglandi. GSM modülünün arti ucu ise pilin giris kismina anahtar koyularak baglandi. GSM modülü 5V ile çalisamadigi için (5V fazla geliyor.) ve yüksek akim çektigi için step-up modülden degil direkt pilin 11 girisinden alindi böylece 4.2V kullanildi. GSM modülü hariç diger bütün sistemler Step-up modülünün çikisindan besleniyor. Bir tane daha PNP Transistör eklendi. Kullanilan 3 transistörün de base uçlari 220 ohm dirence bagli, emitter uçlarinin hepsi Step-up Modülünün artisina bagli, yeni eklenilen son transistörün collector ucu ise ARDUINO'nun A0 giris pinine bagli yani ses sinyali verildiginde Arduino bu sesi son eklenen transistörden aliyor. Aldigi bu sinyali isleyip belli bir voltaj degerine dönüstürüyor daha sonrasinda bu voltaj eger Arduino'da yazilan koddaki voltaj degerlerinin arasinda bir degerde ise ses sinyali o voltaji RX ve TX pinlerinden GSM modülüne gönderiyor. GSM modülü de bu voltaji algilayip SMS gönderiyor. Bluetooth Modüllü Kontrol Basligi için; Aldigimiz ses sinyalini Android yazilim kullanarak bir Android telefon üzerinde bir Arduino ve HC-06 Bluetooth Modülü vasitasiyla haberlestirip. Ilk önce sinyali Arduino NANO'ya gönderildi (kirmizi lede gelen ses sinyalini). Arduino NANO'da bu sinyali PWM olarak isleyip (Puls Width Modulation). Konusma siddetine göre olusan voltaj artisi ve düsüsüne göre Arduino NANO bunu yazilan yazilima göre PWM sinyali olarak algilamaya basladi. Yazilan yazilima göre isler ardindan koda dönüstürerek, bir ses siddeti programina entegre etmemizi sagladi. SUS Uygulamasini telefona yükledikten sonra Bluetooth'tan yazilan Android yazilimina haberlesme saglandigi andan itibaren veri akisi baslar. Bu veri yine PWM sinyali ile gider. Yazilimda Bluethoot'un siddetini 0 ile 10 arasinda voltaj degeri bildirdik. Bundan dolayi mikrofona ses gittigi anda ses sinyali sayisal volt araligina çevrilir ve konustugumuzda uygulamanin sol altinda yazan sayilari olusturur. Mesela gelen sinyalin sayisal karsiligi 1 ise biz ekranda 1 rakamini görürüz. Led siddet göstergesi de gelen sinyalin siddetine göre yanar. Ve ekranin altinda bilgi mesajinda 'SES VAR' mesajini görürüz. Biraz daha yüksek sesle konusursak Arduino NANO PWM sinyalini Bluetooth'a 2 ya da 3 olarak Android yazilim Bluetooth'tan aldigi bu veriye karsilik yine 'SES VAR' mesajini gönderir ama bununla birlikte sol altta yazan 2 ya da 3 olur ve uygulamada sembolik olarak yanan led sayisi da artar. Android uygulamanin ekraninda led siddeti 10 kademedir. 10 tane sembolik led vardir. Onun sol altinda ise gelen ses siddetinin voltajdan bir matrix yazilim sistemine dönüstürülmüs hali vardir. Bunun da araligi 0 'dan 10'a kadardir. Hiç konusmadigimiz zaman ses siddeti O'dir ve uygulamanin mesaj kisminda 'SES YOK' yazar. Program Wifi kullanarak SMS atmasi için kodlandi, ve bu sistem ayni sinifta birden fazla kontrol basligi kullanilabileceginden kontrol basligi numarasi ve SMS'in gönderilecegi telefon numarasini seçebilmek için programa ek özellikler eklendi. Maliyeti düsürmek ve her kontrol basligi için ayri sim karti almaktan kurtulmak amaciyla yeni bir uygulama olan Wifi-SMS gelistirildi. Ögrencilerden çikan ses frekanslarini dinleyen SUS cihazlari Wifi SMS'in olusturdugu Wifi agina baglaniyor ve SUS cihazinda ses algilandiginda, Wifi SMS'in çalistigi cihaza Wifi agini kullanarak içinde SUS cihazi ögrenci isim ve numarasi gibi bilgiler barindiran bir sinyal göndermekte, bu sinyali alan Wifi SMS programi sinyalin geldigi cihazdaki SUS cihaz numarasi ile birlikte ögrencinin velisine SMS atarak veliyi ögrencinin sinif içerisindeki kural ihlali hakkinda bilgilendirmektedir. Bulusun Sanayiye Uygulanma Biçimi Yukarida detaylica bahsedilen " Kendinden GSM, BLUETHOOT VE WlFl-SMS MODÜLLÜ KONTROL BASLlGl " baslikli bulusumuz sanayinin herhangi bir dalinda üretilebilir, kullanilabilir ve uygulanabilir niteliktedir. TR TR DESCRIPTION CONTROL HEAD WITH GSM, BLUETHOOT AND WIFI-SMS MODULE Technical Area Disciplinary problems due to disruptions in classroom management are the biggest obstacles that cause education to be unsuccessful. The social and cultural values of the society are rapidly deteriorating due to the misuse of rapidly developing technology. As a result, it puts secondary school students in adolescence into identities that will disrupt discipline in the classroom. Many items are listed to ensure classroom management and discipline in schools. Some of them; such as an activated education and training environment, an activated guidance system, an activated parent-school cooperation, the use of the school building for social-cultural activities, and the operation of constructive school discipline rules. But unfortunately, when it comes to practice, everything remains written on paper and therefore cannot have an impact on students. The invention is a new technological device that, for the first time in the world, eliminates all problems in the field of education and training related to teacher-student communication in a classroom, by simultaneously coordinating with the student's parents. The software is related to an electronic system network that is original with its technological design, has an effective application area, has a versatile technology aspect, is simple to use, and works as a Wi-Fi SMS program with a single SIM card via both Bluetooth and GSM. Prior Art According to Klausmeier (1992), the teacher, as the leader of the group in the classroom, is the person who has to keep the current atmosphere under control. In schools where a discipline culture is not established, teachers have to deal with the disciplinary problems created by rebellious and overactive students instead of focusing on education and teaching. According to Edwards (1997, cited in Celep, 2004), students may generally cause disciplinary problems in the following situations: Students feel meaningless in their learning. They may cause problems if they find themselves in a difficult environment and do not have someone to help them learn to think independently. There are opinions that it may cause discipline problems when students are made to do exercises on courses they do not like and when punishment is prioritized, and that it has a relationship with the invention, but since the invention was developed and applied for the first time in the world, there are only opinions supporting the invention, there is no previous technique. Purposes of the Invention Our invention is a control head with GSM, bluethoot and Wifi-SMS modules that has been developed to eliminate the drawbacks identified above, and is not only useful but also has an easily portable size and weight. The invention, for the first time in the world, allows the teacher to instantly control the student as well as the parent to determine the student's situation in the classroom synchronously and simultaneously with the teacher and the student. Our aim is to show that the disciplinary problems that occur in classrooms and cannot be prevented, and that negative behaviors that disrupt classroom management can be prevented with a different method, with the new technological tool SUS that we have developed, and to make it compatible with the Ministry of Education curriculum and ensure that it becomes widespread. New technological materials and new formations are important as the education-training process has come to a halt or even a halt due to discipline problems in the classroom. It is directly related to the future of the country.

Then, the condenser microphone was placed at the end of the device and the device was wrapped with insulating tape to prevent damage to the sensitive cables. The control remote and the boxes where the circuit will be placed have been brought to a useful and lightweight form with the help of a router. In order for each stage of the invention to be unique, instead of using a ready-made headset, the design of the control head was added to the prototype by considering the combination of different parts. There are 4 LEDs and one lithium battery unit. The lithium battery unit operates with one 3.7 volt battery. It has a rechargeable input with a Samsung charger and a Bus Converter on the extra lithium battery unit. Bus Converter is a converter that increases 3.7 volts to 5 volts and also allows the battery to be charged. 7 volts taken from the Bus Converter are given to the Mic Preamp Module. The preamp multiplies and amplifies the audio signals we send from the microphone, thanks to an Opamp integrated on it, and then gives us a voltage value. In other words, when we speak in a low voice, it may increase to 1-2 volts, and when we speak loudly, it may increase to 4-volts. The purpose of this is to adjust the brightness of our red LED according to the intensity of the sound signal we speak. If we talk in a low voice, the red LED lights up less (dimly), if we talk loudly, the red LED lights up more (higher). Then, after entering the voltage from the Step Up Converter into the Preamp Module, we used a PNP Trasistor. We used two transistors. One of them triggers the red LED, the brightness of the light decreases and increases according to our conversation volume, and the other one triggers the Buzzer. The buzzer also makes a sound according to our sound intensity. At high volume, it produces a high return signal sound and at low volume, it produces a quieter sound signal. However, apart from the red LED, we have three more LEDs. These are: yellow, blue green. These LEDs work completely independently of the sound system. We placed 3 buttons on the box, matching the colors of the LEDs. By placing a 620 ohm resistor between the 7 volt voltage we received from the Bus Converter, we reduced the current (according to the operating voltage of the LEDs). The 620 ohm resistor served as current limiting. All of our buttons were entered with a parallel "+" input at one end. Then, we gave the other positive ends of the buttons to the positive inputs of each LED. We combined the negative ends of the LEDs and transferred them to the negative end of the Bus Module, which increased the voltage to 7 volts, and thus the circuit was completed. We have 3 buttons, green, yellow and blue, the same colors as the LEDs. Whichever button we press on this remote control, the relevant button has the task of turning on the relevant LED, regardless of the sound signal. For Control Head with GSM Module; For the GSM module, the d10 and d11 inputs from ARDUINO are connected to the RX and TX pins on the GSM Module. Since the minuses used throughout the circuit are common, the minus cable on the GSM module and the minus cable on the ARDUINO were combined and connected to the main minus lead. The positive end of the GSM module was connected to the battery input by placing a switch. Since the GSM module cannot work with 5V (5V seems too much) and draws high current, it was taken directly from the 11 input of the battery, not from the step-up module, so 4.2V was used. Except for the GSM module, all other systems are fed from the output of the Step-up module. One more PNP Transistor added. The base ends of all 3 transistors used are connected to a 220 ohm resistor, all of the emitter ends are connected to the increment of the Step-up Module, and the collector end of the last newly added transistor is connected to the A0 input pin of the ARDUINO, that is, when the sound signal is given, Arduino receives this sound from the last added transistor. It processes this signal it receives and converts it into a certain voltage value. Then, if this voltage is between the voltage values in the code written in the Arduino, the audio signal sends that voltage to the GSM module from the RX and TX pins. The GSM module detects this voltage and sends SMS. For Control Head with Bluetooth Module; We communicate the audio signal we receive with an Arduino and HC-06 Bluetooth Module on an Android phone using Android software. First, the signal was sent to Arduino NANO (the audio signal coming from the red LED). Arduino NANO processes this signal as PWM (Pulse Width Modulation). According to the voltage increase and decrease that occurs according to the speech intensity, Arduino NANO started to detect this as a PWM signal according to the written software. The work was then converted into code according to the written software, allowing us to integrate it into a sound intensity program. After installing the SUS Application on the phone, data flow starts as soon as communication is established via Bluetooth to the written Android software. This data goes again with the PWM signal. In the software, we reported the intensity of Bluethoot as a voltage value between 0 and 10. Therefore, as soon as the sound goes to the microphone, the sound signal is converted into a digital volt range and when we speak, it creates the numbers written at the bottom left of the application. For example, if the numerical equivalent of the incoming signal is 1, we see the number 1 on the screen. The LED intensity indicator also lights up according to the intensity of the incoming signal. And in the information message at the bottom of the screen we see the message 'THERE IS SOUND'. If we talk a little louder, the Arduino NANO sends the PWM signal to Bluetooth as 2 or 3. The Android software sends the message 'THERE IS SOUND' in response to this data received from Bluetooth, but at the same time, the text written at the bottom left becomes 2 or 3 and the LED that lights up symbolically in the application The number also increases. The LED intensity on the screen of the Android application is 10 levels. There are 10 symbolic LEDs. At the bottom left of it, there is a version of the incoming sound intensity converted from voltage into a matrix software system. Its range is from 0 to 10. When we do not talk at all, the sound volume is 0 and it says 'NO SOUND' in the message section of the application. The program was coded to send SMS using Wifi, and since more than one control head can be used in this system in the same class, additional features were added to the program to select the control head number and the phone number to which the SMS will be sent. A new application, Wifi-SMS, was developed in order to reduce costs and avoid purchasing separate SIM cards for each control head. SUS devices, which listen to the sound frequencies coming from the students, connect to the Wifi network created by Wifi SMS, and when sound is detected in the SUS device, the SUS device sends a signal containing information such as student name and number to the device where Wifi SMS is running, using the Wifi network. The Wifi SMS program that receives this signal It sends an SMS to the student's parent along with the SUS device number on the device from which the signal comes, informing the parent about the student's violation of rules in the classroom. How to Apply the Invention to Industry Our invention, which is mentioned in detail above, titled "CONTROL HEAD WITH OWN GSM, BLUETHOOT AND WIFI-SMS MODULE", can be produced, used and applied in any branch of industry.
