Hi everyone,
I am controllering a brushed dc motor with a dc motor controller that accepts PWM. Immediately when the controller gets a PWM signal from the arduino, the motor gives off a high pitch noise. I tried this with multiple motors and it does the same thing. I googled the issue and it seems that it's related the output of the Arduino pwm frequency...that it's frequency is too low.
Has anyone overcome this or know of a reason why this is happening?
Is it really the arduino or the motor controller?
Thanks
