Lesson-6 : How to Use a Push Button with Arduino | digitalRead() Explained

Описание: Lesson:6 - How to Use a Push Button with Arduino | digitalRead() Explained

Hello and welcome to Electro Nerds Academy! In this beginner-friendly tutorial, we'll show you how to connect a push button to an Arduino and control an LED based on its input using the `digitalRead()` function.

This is an essential project for anyone starting with Arduino, and it teaches you how to handle digital inputs, fix floating pin issues, and use pull-down resistors for reliable readings.

What You’ll Learn:

✅ How to connect a push button and LED to Arduino
✅ Understanding how a push button works internally
✅ Why floating pins cause false readings — and how to fix them
✅ How pull-down resistors help stabilize inputs
✅ Using `digitalRead()` to detect button presses
✅ Using conditional statements (`if/else`) to turn the LED on or off
