Wat is it?

This is my version of the Nanopops based on the code by Jan Ostman.
It's a simple mini pops like rhythm box based on an Arduino Nano.

Nops drum box



In my design I used simple on/off buttons to mute the sounds played.
I adjusted the code to my own needs and design.


I refactored a part of the code, added comments for my self.
For example the original code starts playing when powered and the start/stop works as a mute. I changed the function so the Nops initially is muted and starts playing when the button is on. The code needs fixes, but it works. In the original code the tempo pot is wired the wrong way. I will fix that soon.
License, I like the BSD style licences, but Jan Ostman shared his code under a non-commercial license. So I placed changes I made under the creative commons license.
