This project is the most basic Arduino program where an LED is made to turn ON and OFF repeatedly. The Arduino sends a signal from one of its digital pins to control the LED. When the pin is set to HIGH, the LED glows, and when it is set to LOW, the LED turns off. A delay is added between ON and OFF states to create a blinking effect.
This project helps students understand the basics of programming, digital output, and how Arduino controls electronic components.
