Hi everyone!
This is a project I finished recently: A universal Bluetooth remote for android.
I think it will help a lot of people that want to control their Arduino over Bluetooth.
Most controllers I have seen on the Play Store have a fixed layout, so if you wanted a customized remote you had to program it yourself. With my app you can drag and drop UI elements on the screen, change size, color and much more. It has full multitouch and 8 save slots for controller layouts. You can basically control every Arduino project with this.
The app is programmed using Processing for Android, I made the user interface and multitouch handling from scratch in about 1200 lines of code. Only the Bluetooth communication makes use of a library.
The app is not available on the play store, you can find instructions and the download link to the .apk on my blog post:
