Wireless Communications to Garage Door

Postby V8mgb » Sat Nov 29, 2014 5:15 pm

I set up a low tech wireless communication system for my garage door. I still need to clean things up , here is what I did

- Relay connected to a door opener (what you would normally use in your car). When the relay closes it activates the remote to open / close the door
- I am using a set of NRF24L01 wireless transmitters to communicate / send door open / close position.
- Magnetic sensor attached to door opener trolley
- Needed a 2nd Arduino to receive the door position data which is connected to the Arduino and Ethernet running the My Door Opener code
- NRF24L01 and Ethernet used several of the same Ardunio pins which required me to add the additional Arduino
- Used all low cost ebay Arduino boards and Ethernet shield
- The NRF24L01 could also be used to trigger the door open / close. I wanted a more secure communications for this but I am sure something could be put together


Here are the major components

Arduino Boards $5.95

Ethernet shield $12.99

NRF24L01 High Power $4.95 (reference this page : http://arduino-info.wikispaces.com/Nrf2 ... 4GHz-HowTo )

NRF24L01 Socket adapter $1.04 (need this for the 3.3V regulator)
