In this guide we will use the Circuit Playground to create a bike turn signal indicator. By sewing the Circuit Playground to a bike glove and using the accelerometer to detect hand position the standard hand turn signals are enhanced with some nice NeoPixel animations.

Required Parts

In addition to a Circuit Playground, you will need some form of battery power. The 500mAh battery is a nice low profile option and is recommended for this build. However, you may be able to also use the AAA battery pack if you can incorporate it into your bike gloves. Oh yeah, you'll also need bike gloves and some needle and thread to sew everything together.
