enter image description hereI am working on a brushed motor quadcopter using Arduino pro mini.

Every time I try to throttle, the Arduino gets reset by itself (motors start to spin but they will be turned off in 2 sec). I have added a 1000uf capacitor (tried up to 3300uf) to the input of Arduino VCC and GND. But still having the same issue.

  • Do you have suppression capacitors on your motors?

    Sounds like a power issue. Are you using the same battery for the motors and Arduino? If yes, Can you try a different battery/power source for arduino?
