Green light turns on when power is supplied
Red light when time expires
I want to put a momentary/ slide switch so that when its pressed the unit is "reset". I was told I need to put a resistor "in series" with the switch to prevent short circuit. How much of a resistor do I put? Im using a 9 volt batttery. and what do I attach the switch to?
