Introduction
If you are new to Arduino and electronics, the LED blink project is the perfect first step. Known as the “Hello World” of Arduino, this simple project introduces you to both hardware and coding. In this tutorial, we’ll walk you through setting up your Arduino and making an LED blink without using any external resistor.
By the end, you’ll have your first working project and the confidence to explore more advanced Arduino experiments.
What is Arduino?
Arduino is an open-source electronics platform that makes it easy to create interactive projects. With just a few lines of code, you can control lights, motors, sensors, and more. It’s widely used by beginners, students, and makers worldwide.
