If you have a lot of button inputs for a project, keeping track of them (whether theyâ€™re pressed, just pressed or just released) and debouncing can get a bit hairy. here is some sample code that will keep track of as many buttons as youâ€™d like. The example shows 6. To change the pins or number of buttons, just put them in the array called â€œbuttonsâ€ and the rest of the code will automatically adjust. (The code is in Arduino-ese but its pretty much just straight up C) Enjoy!
