## Description

The Brightness Cubelet has an analog photocell that responds to varying light conditions and detects the amount of light hitting it’s sensor. Expect values near zero in a dark room, and values near one when the sensor is in front of a bright light.

 Cubelets are magnetic blocks that can be snapped together to make an endless variety of robots. You can build robots that drive around on a tabletop, respond to light, sound, and temperature, and have surprisingly lifelike behavior. But instead of programming that behavior, you snap the cubelets together and watch the behavior emerge like with a flock of birds or a swarm of bees.

**Note:** Cubelets require a special battery and charger. You will need to purchase the [charger](https://core-electronics.com.au/search/?q=11344) separately.
