WebJul 28, 2024 · The program is tracking the state of the switch. So you need to know the previous state of the switch to know if the state of the switch has changed. Also please explain the working of a code in a brief manner in a loop. The two fixed or reserved function names in an Arduino sketch are "setup" and "loop". "setup" is called only once on boot up. WebMay 17, 2024 · #define INPUT_PIN 0 // digital input pin 0 bool state = false; void setup () { ... pinMode (INPUT_PIN, INPUT_PULLUP); ... } void loop () { ... if (LOW == digitalRead (INPUT_PIN)) { state = ~state; // toggle state } if (state) { ... // work } } This code implements a classic strategy known as polling.
