yeah I already saw it... So I just need a 40 ohm resistor if I gonna make a direct wiring for my O button to be non reactive on a 5v points...
so L&R leds will go with the LM386 on the Anode + and my unreactive O button will go to either 3v or 5v with 40 ohm resistor on power switch board?
and All of my Cathode will get bridge to the wire of Wifi Switch...
I am just thinking where does the Ground pin on LM386 goes?
