Changing pwm signal frequency affects motor's
WebMay 6, 2024 · Why not, it is a prescaler if affects everything that follows it. Well, to be honest, I thought Serial drew it's clock directly from the main 16MHz crystal. There's also this post by RuggedCircuits. I was under the impression that changing timer0 only changed the delay () and millis () functions. Hey. WebMay 6, 2024 · The sound is created from the motor and the shield. A solution is to change the PWM frequency on the PWM pin used. If the PWM is above 20kHz humans cant hear it. The problem with changing the PWM frequency is that timers are changed and with the timer-change functions like delay() is changed. Different digitalPins have different PWM …
