Project tutorial by dtbaker. A relay board to activate the opener this acts like a wall switch or button but the etherten pushes it instead of you. Garage shutter door and light are activated by user. In this video i re engineer a 40mhz garage door opener and build a small one for my harley.

Connections are not difficult. In this project we will be using the power of rfid to tap into your garage door opening system. So we tought about our last project where we successfully made arduino talk with raspy using nrf24l01 and dumbly toggling lights. 433 92mhz rf transmitter and receiver pair i got mine from ebay for the ridiculously cheap price of 1 45.
