62. Single Double and Long Press with Interrupts

Build a task using a microcontroller  to detect single, double, and long presses of the push button switch with the following requirements:

• Push Button Press Actions 
  • Single press → toggle LED 1
  • Double press → toggle LED 2
  • Long press → turn OFF both LEDs. (more than 1 second)
• Button Debouncing: Implement debouncing to prevent multiple detections from a single push button switch press.

Main Loop Constraint:

The controller is constantly busy executing critical tasks inside the while() loop in the main function, as shown in the code below, so use Interrupts to implement tasks.

main () {
  while (true) {
    //In this loop Microcontroller is busy in monitoring and performing critical tasks constantly.
  }
}
