Arduino + LDR + Python + RhythmBox

In this video, I use the LDR circuit with the Arduino Leornado to control the RhythmBox player on my Ubuntu laptop. The Arduino writes LDR values to the serial port, which are read on the laptop by a Python program, which in turn uses dbus to control RhythmBox. This app does not do much. It merely pushes the player over to the next track with a hand gesture. More functionality will be added to the app soon.
