Hi,
Keep all low voltage arduino wires well away from any AC wires associated with the flipper.

The closest the two systems should get is where the arduino wiring connects to the relay on one side and the relay to the AC on the other.

If you have a rats-nest of wires, then that won't help either.

Tom.... :slight_smile:

thanks for suggestions
