Hello everyone
I've been searching the web about DC motor control, and found PWM is an easy way to do it......
So, I understand what PWM is...... and finding a suitable circuit isn't a problem......
But something that keeps bugging me is; how do we change the speed by changing the duty cycle, I mean when the voltage is at a low 0V shouldn't the motor actually stop???
Does it have to do with the frequency of the signal if you may?
Thank you
