During a hackathon at Thalmic Labs I built MyoDuino to allow the Myo Armband to control an Arduino.  After the hackathon I cleaned up the code and Arduino library a bit and published it on the Myo Market.

After that it was featured on MyoCraft, a weekly blog featuring cool applications of the Myo.  The post here goes over the setup and an example, it also shows the pose icons cut outs that I built during the hackathon.

The application, source code and suporting application can be found on the downloads page.
