Use a Button to Toggle an LED | Arduino push button Programming | toggle switch programming

This code sets up the switch on digital pin 2 and uses the built-in pull-up resistor to ensure a stable input signal. The loop function checks the current state of the switch and compares it to the previous state. If the switch state has changed, the code toggles the state of the built-in LED on the board. A small delay is added to debounce the switch and prevent multiple toggles from a single press.
