Arduino BT Control

Another example of controlling the Arduino from an Android app via blue tooth.

2 examples;
1, a basic turn LED on and off,
2, turn lots of LEDs on and off.

The Arduino code is fairly simple and should be easy to understand. All files, including the app inventor aia file, are available for download.
