The most common reasons for instability are: Insufficient decoupling capacitors. WebAug 31, 2014 · If you want to simplify you circuit you could instead use a pull-up resistor, and connect the button to ground instead of 5v. The ATMega chip on the arduino has these pull-up resistors build into the chip itself, so you don't need to add one to the breadboard. Just not that the input values will be reversed. celebrity sensation
