How to Use an Arduino

The skills it targets

This playlist starts with setting up and programming an Arduino, then moves to building circuits that use LEDs, buttons and potentiometers. It names four core commands along the way: digitalRead, digitalWrite, analogRead and analogWrite.

Why those four commands matter

Digital and analog input and output cover most early Arduino projects, so getting comfortable with these functions is a sound first step. Each command pairs with a simple part: a button for reading a digital state, a potentiometer for reading an analog one, and LEDs for writing output.

Where to go next

• Rebuild each circuit on a breadboard before moving on
• Change one value in the code and observe what happens

The playlist is aimed at beginners and presents itself as groundwork for more advanced Arduino projects.
