help me control DC motor speed

[wazzaw]

i have two DC motors, one is faster than the other so i want to slow down the faster one. I am using pic16F877A to control these motors.

I need help on how to control the motor using PWM, how to set the duty cycle and how to output this PWM on a pin.

I am using MikroC. Any help please.

Hi

Generate PWM signal using the timer and set the signal to motor driver

If you currently using the timer you can generate PWM using software

All the best

If the motors are meant to drive a load, an open loop control will not do. You can set up an optical interrupter sensor on the motor for the controller to know the present speed and know which way to adjust the duty cycle
