I'm currently working on a new Arduino shield - & I thought I'd share a preview video with everyone on the Arduino forums:
The shield is a programmable digital synthesizer, with many great features - It's called the Ronin 802
The Ronin 802 shield can be stacked and multiple shields can be controlled by a single Arduino.
It is a very flexible platform for building electronic musical instruments.
More information on this project (including schematics and code) will be available soon.
Just a quick update to let you know that the Ronin 802 synthesizer shield is now available to buy!
