Introduction: Velophonic Wheel

By

Velophonic is a musical bike project that encourages cyclists to make their own motion instruments to explore the city with an enhanced ride.

For this project we are going to use an Arduino and piezo sensors to make a mechanism that can be attached to your bicycle and plays a melody when you are riding it. The mechanics are similar to those of a music box except it plays digital sound files instead of acoustic sounds.

You can build it as it is or use it as the starting point of your own motion music instrument. We hope you like it and please, share photos and videos of your version with us!
