Android IOIO Digital Output

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.

Eclipse and I are still having our issues, but the ADK is becoming less Greek to me. The next project should shed some light on what sort of possibilities IOIO presents.

Well, long story short. I put together the little POC using my PIR sensor a while back. The shit deal, is that the sucker only writes high and low. Easy, for the win. Limited, for the loss.

I may or may not have (I did) disassembled a few CRT TVs last month. Hence, have all sorts of components, such as small sub 9V speakers…

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.
