I got bluetooth working last night on the clock really quickly. Steps are as follows.

1. Plug in bluetooth board to Arduino programming ports, 5V to 5V, GND to GND, RX to DOUT, and TX to DIN.
2. When the clock is powered on, the bluetooth board should light up and you should be able to pair with you...

Clock is done. It's not perfect, but it works.

So far with the clock.

Finished building my desktop.
