Important Notes:

The RN-24-E Bluetooth module in this design has been discontinued by Roving Networks. I would suggest using either a RN171XV (WiFi) or a RN41XV (Bluetooth) module in its place.
The strips and electronics are powered through a 12V DC/DC converter similar to the Cui VYB15W-Q24-S12-T. This device has an input range from 9 to 36VDC and an output of 12VDC. This is there mainly to protect the LED strips against the unregulated voltages that are encountered in a vehicle's quote-unquote 12V electrical system.
