Stepper motor + DC motor + button + brightness sensor + AD + BCD digital tube
controls the stepper motor and DC motor through 4 independent buttons. Button 1 controls the direction of the stepper motor, and button 2
clockwise and counterclockwise controls the direction of the stepper motor.
Speed, fast and slow
buttons 3 control the direction of the DC motor, clockwise and counterclockwise
buttons 4 control the speed of the DC motor, fast and slow are
timed by hardware timers, every 5 seconds, through APDS-9002 or TORCH_LDR, AD The brightness value
collected by the module
is sent to the host computer (virtual terminal) through the serial port with a baud rate of 9600bps (note that the crystal oscillator of
the microcontroller is set to 11.0592MHz)
