The Complete Beginners Guide to Arduino - 2021 - Blink 3 LEDs - Using Delay

The video tutorial demonstrates how to expand a simple LED circuit from one to three LEDs. It covers the setup of the circuit on a breadboard, including the necessary components like resistors and jumper wires. The tutorial then guides viewers through programming the LEDs to blink in sequence using an IDE, with detailed explanations of the code. Testing and modifying the code to achieve different LED patterns is also discussed. The tutorial concludes with a summary and hints at future projects using different techniques.
