I am one coding session and one EE session away from having a pretty cool project to post. In the meantime, I am making some progress with the IOIO.

I’m trying to do something with a dual speaker setup, in order to shine up my bugler alarm project. The code is boring…stay tuned…I might be able to come up with something amusing.
