This is a fun and simple beginner project that turns the Circuit Playground into a cold temperature indicator. It uses the on board temperature sensor to read the current temperature. The coldest temperature measured is indicated on the NeoPixels.
An additional sketch is provided which turns the Circuit Playground into a temperature data logger.
Required Parts
This project uses the sensors already included on the Circuit Playground so no additional electronics or soldering are required. You will also need some batteries and a holder for the batteries.
- Circuit Playground
- 3 x AAA Battery Holder
- 3 x AAA Batteries (NiMH work great!)
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.
