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.

+1 a bunch of wires

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.

I shot a video of one of my debugging tests. I eventually will be using an ‘open drain’ setup, in order to get 5V output, but am doing some testing at 3.3V. I hooked up an old speaker that I salvaged from a CRT tear-down to my test pins, to verify that my Android App was working.

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…


the wires are wire-y

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.
