I re-did the wiring in the garage as well. I used to have a spiderweb in the ceiling with droopy wires from the access door to the openers. Who ever installed the openers or the wiring must have run out of staples, and there were like 3 for the two openers. Now all the wiring goes through the attic, with the central wiring on a barrier strip.
The sketch I didn't change, but I noticed I didn't upload that either. I'll give that a go as well. The sketch isn't doing anything really complex. It is still based on ardudroid.

One relay each on pins 7 and 8. The power supply is my old Motorola Razr charger (mini USB). The HC05 is connected using the TX and RX serial pins, so they need to be disconnected if connecting to the USB port to program the Arduino. Also Have a look at the Ardudriod page for the resistors and 3.3V connection. (Don't try 5V and don't forget the resistor on the RX pin). Remember the module is receiving on RX but sending to the TX pin.
There have been a few things I don't like about it, but overall it is serving it's purpose. Pairing basic HC05 modules with and Arduino isn't as quick or automatic as I'd like it to be. Of course, sometimes the signal is going through an aluminium door on the way to the module, so I can't blame anything but circumstances.
If you are thinking of trying this yourself, I recommend it. If nothing else, this is a good place to start.
