+##V1.1
+[![Lightning cloud v1.1](http://i.imgur.com/i8TT3HJ.png)](https://www.youtube.com/watch?v=XI98PhaZPTs "Click to see the video")
+
+Added control via Bluetooth Low Energy module. When you type the letter "f", the lightning "f"lashes.
+[Instructable for adding BLE control available here.](http://www.instructables.com/id/How-to-Add-Bluetooth-Control-to-your-Lightning-Clo/step6/Test-with-the-Adafruit-BLE-app/)

+To check out v1.1, use the following command:
+
+$ git checkout -b branch_name v1.1
