Arduino Beatdet
This 4 channel Arduino Beatdet (bidet) rocks your spots off. Select a beat on your phone and the Beatdet will jam out while it cleans you out. The Pirate Radio Bellagio of bidets. Authentic streaming music. Beatdet Pro allows you to choose any track on your phone to wipe with.


Notations
1. Considerable thanks to MakerBar in Hoboken, New Jersey.
2. It should be noted that this, as are most of our projects, a prototype, and surely demands several refinements; for example, superior nozzles for a more effective spray.
