Lesson14 Switch LED INPUT PULLUP Push to ON, Push to OFF

In this tutorial, learn how to use a push button with INPUT_PULLUP mode to toggle an LED ON and OFF with each press using Arduino. This method simplifies wiring by eliminating the need for an external pull-down resistor. One press turns the LED ON, the next turns it OFF.

🔧 What You’ll Learn:

Using INPUT_PULLUP to simplify button wiring

Detecting button press with active LOW logic

Toggling LED state on each button press

Basic switch debouncing for reliable input

📌 A clean and efficient approach to building toggle-based LED control with minimal components!
