Case for solderable breadboard that holds my circuit:
https://www.tinkercad.com/things/d0vNP6qnxQN-super-habbi/edit? (STL is attached)

The circuit is super simple. There's an arduino nano, a 5v/3v level shifter, and an HC-05 bluetooth module, all soldered into a solderable breadboard.

That contraption talks to my android phone via Software Serial. There's a photo of the circuit attached. I'm happy to draw it out if you leave a comment and ask for it, or feel free to ask questions.

The arduino nano uses a 5v/3.3v level shifter like this one to drop to 3.3v for the HC-05 bluetooth module, since that module isn't rated for 5V logic (it's okay to give it 5V power):

The tape on the various components is hiding the arduino and bluetooth status LEDs.

This was my first attempt at messing with Android apps, so I imported Mantas Palaima's excellent bluetooth arduino app as a starting point. I've committed the changes I've made so far, and will have more to come:

The arduino code to control the lights themselves is here:

Oh, you're one of today's lucky 10,000!
