Hi,
how to find the value of capacitor to reduce the electronic interference?
I added 600/1000uf Electrolytic Capacitor; 0.22uf/10uf ceramic capacitor; mixed them etc, seems no much improve.
Thanks for help.

How are you powering this setup? Are you using the DC power jack?

It would help to tap power direectly from the jack on the back side of the board instead of from the pins. The caps are fine as is, a big and a small is best. A small resistor (100 ohms?) between the jack and the caps might help too.

I used KF2510 connector M/F to connect power of battery bank with common GND to Arduino.
I'll try 100 ohms.
