GitHub - bluehat/Serial-Relay-Controller: Controls a relay via a serial port. Written in python, currently works with demo code to read from a USB RFID reader and control the relay if the ID is found on a list it pulls from the internet. Please note that the file opened by pyserial is particular to my system, which is a linux box with a USB to serial adapter. You'll need to find the appropriate file on your system. Also please note that this assumes your relay circuit is connected to DTR or pin 4 on your standard 9-pin serial connector. There is a second pin you can use on the serial port if you want to control two relays.
