This project was made for stylish individuals who want to stay safe. Make your own by combining littleBits with craft material. Then, wear the mystical bike helmet to light your way when you ride at night.
littleBits is an open source library of electronic modules that snap together for prototyping, learning, and fun. Each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc.), and the modules snap to make larger circuits. littleBits are sold in kits, which are available in the Maker Shed.
