Code So, I grabbed a Mega and several pushbutton switches (one of which turned out to be a push-on, push-off, much to my bemusement), and ginned up a small Arduino program to illustrate an interrupt-driven button I found a 2018 demo of using read history to debounce multiple buttons, see if you like it. Many switches of the style you're using are hard to debounce well, and trying to use a resistive multiplexer won't make it easier. Two things you've missed are you've declared 2 variables with the millis function and to use it to control the program flow based on some condition to execute some code, in your case, to press 2 buttons to turn on and off an LED. The sketch will therefore support as many button 29 switches as a microcontroller can provide digital inputs. I tried modifying the debounce function to receive a pin number and debounce that pin, but for whatever reason it wouldn't debounce more than one button, now i tried making a separate debounce function for each button and calling each one and it works. The tutorial provides code in two ways: Arduino multiple buttons with debounce using arrays. Using direct register reads is a faster way on every arduino, it can be useful to do that.
