Single Switch Multiple Functions

Introduction

In this project, I am going to teach you how to give multiple functions in a single push switch. Below is the list of different ways of using the switches for different functions,

• Single Tap
• Double Tap
• Triple Tap
• Four Tap
• Hold
• Tap and hold

Things Required

• Arduino or any other compatible board
• Micro push button
• RGB LED, for testing the switch functions.

Theory

• First, we calculate the time gap between each button press and the number of times the button is pressed 
• Then according to the no. of times, the button is pressed we are calling different functions
• like the same way if the time gap is more than the preset value then we consider it as a "hold" and we call the functions which we associate to it

Circuit

• Connect one leg of the push button to any digital pin.
• connect the other leg to the ground of Arduino.
