Module 1

Welcome to Arduino

Welcome to your first step into the world of electronics.

In this module, you will learn how to use an Arduino Uno, connect components safely, write your first program, and build confidence using a breadboard.

You do not need any prior coding or electronics experience. Each challenge takes only a few minutes. By the end of Challenge 10, you will have completed your first electronic projects completely on your own.
