Here is a schematic of the hardware and how its hooked up.
2) this is a diode used to protect the hardware from unwanted emf signals.
3) an NPN transistor used to provide enough current for the relay coil. The coil relay requires more current than the Arduino output pin can provide.
Bluetooth works just outside my home, but ideally I want to control the garage from anywhere I want. I will be modifying my App in order to communicate it with a computer through the internet. Stay tuned...
