“follower” wrote in with yet another cool project for the Android Open Accessory SDK. This time, you don’t even need to do any Android programming; your Arduino Sketch tells follower’s Android app what to do and what to display on the screen:

Handbag makes it possible to create Arduino-based accessories for Android devices without creating an Android app. You both define the Android application user interface and implement the behaviour in your Arduino sketch.

Here’s an example of how you would (currently) create an interface with a label, some space and a single button:

configureWidget(UI_WIDGET_LABEL, ID_NONE, "Example Handbag Android Accessory");
configureWidget(UI_WIDGET_LABEL, ID_NONE, "");
configureWidget(UI_WIDGET_BUTTON, ID_B1, "Toggle Digital Pin 4");
