hey guys, I've built a prototype of my pwm circuit and it all works fine. The problem is that the motor whines at lower speeds which I could guess is too low a frequency. I want to increase the frequency but I'm not really sure how in this case. Could anyone help me? Like what equation do I use to work out the frequency?
Here's my circuit drawing and my prototype:
Thanks, Sam
