In this guide we will use our Circuit Playground along with some alligator clips and a resistor to explore how we can read digital inputs.
No soldering required!
Before Starting
If you are new to the Circuit Playground, you may want to first read these overview guides.
This project will use the Arduino IDE. Make sure you have added the board support for the Circuit Playground as well as installed the Circuit Playground library. MUST DO BOTH. This is covered in the guides linked above.
