WebDec 10, 2024 · 1. You can use while to loop until a button is pressed. Using arrays will make it much easier, here I use an array for leds and a another for buttons. The … WebArduino - Arrays. An array is a consecutive group of memory locations that are of the same type. To refer to a particular location or element in the array, we specify the name of the array and the position number of the particular element in the array. The illustration given below shows an integer array called C that contains 11 elements.
WebMar 18, 2024 · The below sample code presumes that the buttons are connected between GND and the GPIO input pin on the Arduino. Since it's using the internal pullup resistors, no external ones are needed. The one minor issue is that it inverts the state of the buttons -- 0==pressed, 1==released (not pressed).
