Description: DC motor with a microcontroller, you need to add driver circuit, the system uses a Darlington driver, that chip ULN2003A, the chip can drive seven motors, one for each motor from the microcontroller I/O port control. When you need to adjust the DC motor speed, so that the corresponding MCU I/O port PWM output waveforms of different duty cycle.
