In this guide we will use our Circuit Playground along with a potentiometer and some alligator clips to explore how we can read analog signals into our digital computer.
No soldering required!
Required Parts
In addition to the Circuit Playground, you will need some alligator clips and a potentiometer. While not required, a knob makes turning the potentiometer easier and provides a nice reference mark to see where you are at.
Optional Parts
Another option is to use a breadboard along with a trim pot and alligator to male jumper wires. The hardware outlined in the previous section is recommended, but if you already have these items, they will work as well.
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.
