Overview

This is a fun and simple beginner project that uses the Circuit Playground to create a light activated alarm. A diary, or other object, can be placed on top of the Circuit Playground and an alarm will sound when the object is removed.

Required Parts

This project uses the sensors already included on the Circuit Playground. The only additional items needed are batteries for power and a holder for the batteries.

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.
