Android app for Binary coded ASCII characters

I wrote about a project this morning that used a piece of tinfoil connected to an Arduino to simulate touchscreen presses on a tablet. I tried to do this myself but couldn’t get it to work reliably. I had already written this Android app which I intended to use with the interface technique had it work. I can’t unwrite that code so I’ve decided to share it. There’s a description in the video, and here’s a link to the code repository:
