A video demonstration was in order. Power on the antenna was increased to maximum so the tag would read as quickly and easily as possible. In this case, the power was set to 27dBm which is still a measurement which displays during the startup sequence of the machine. It may be convenient to shorten the startup sequence in the future.
Wires were run between the garage door opener's switch contacts and a relay connected to the Arduino and scanner. The dry contacts of the relay behave just like any mechanical switch so the garage door opener will not know if a switch is pressed or a relay is closed.
A short video was taken outdoors. It was a hot day but that did not stop airplanes from flying right over my house. The video was seventy seconds long, just enough time to demonstrate the use of RFID to open a garage door.
The rest of the posts for this project have been arranged by date.
