Automatic Brake Light

Build a bike light with the Circuit Playground. It senses when the bike is braking and lights up NeoPixels when the bike is slowing down. When the bike is at a full stop, the NeoPixels will fade in and out! A 3D printed mount allows you to attach the circuit playground case to the frame of your bike.
