Detailed Description

Example delay timer control using callbacks.

The built-in LED lights up when a button connected between pin 2 and ground is held down for 2 seconds or more. It uses the internal pull-up resistor within an Arduino for the simplest button connection.

When the button is released, the LED stays on, waiting until idle after 5 seconds and the LED goes off. Simulates a delay timer.
