Hi,
I use a Arduino Nano and the 10A Motor Driver single from cytron, everything works just fine, except the Motor sounds in a very high pitched tone, way too loud. By using a PWM controller with Poti and just without any driver i could find out, that the Motor is usualy silent.
Can someone help?
Hi @BobRoss1337 and welcome to our forum!
This issue can be caused by the Arduino output PWM frequency. It could be that the frequency is too low. What frequency are you currently using?
Yes! I asked the question in a german board and found the same out! I added “TCCR1B = TCCR1B & 0b11111000 | 0x01;” if someone got the same problem, it has, just as you said, something to do with the frequency of the Arduino. There are a tone of tutorials in the internet. Thanks!
