Hi.
This is my first post on the arduino forums and I thought it would be good to ask the community for help on my problem.
The problem is that I am trying to control an RC helicopter's motors with MOSFETs. I tested everything on a breadboard and it worked fine. Then I proto-boarded the circuit and it worked. Then I made some adjustments to the wiring and suddenly the MOSFETs ran into trouble.
I turned them on at half speed (analogWrite(pin,125)) and they worked perfect for about 5 seconds and suddenly both MOSFETs became closed (They ran at full speed). I have turned the arduino on and off many times but from now on the don't work at all and just run at full speed.
It is not an error with the code
It probably has shorted somewhere so what I am asking is what causes a MOSFET to make this happen??
Any replies are appreciated
