Abstract

A swing control device comprises a plurality of stage buttons, a plurality of sensors, a built-in microprogrammed control unit (MCU) control unit and a motor. When a swing arm arrives sensing points of the started sensors, signals are transmitted to the built-in MCU control unit, namely the swing arm already swings to a position set by a user. When the user starts the device, the built-in MCU control unit firstly executes a preset swing cycle program before the swing arm arrives the sensing points, and the preset cycle program includes controlling time for forward driving, reverse driving or output pausing of the motor or only driving the swing arm unidirectionally so as to increase swing amplitude of the swing arm continuously. When the swing arm swings to the sensing points of the sensors, the built-in MCU control unit immediately stops outputting to the motor on receiving signals transmitted by the sensors, or transmits the signals to the MCU to control a nest swing cycle of the swing arm so as to adjust output of the motor till the swing arm is detected by the sensor again at the next time. The swing arm is driven according to the cycle program so as to be maintained for stable swinging within a range set by the user.
