I always like to make a wiring diagram (Figure 1: Circuit Schematic w/ LED) using Fritzing, an open-sources schematic capture and PCB routing software. Step-by-Step Guide to Integrating an RFID Module with Raspberry Pi I discuss how this design can be implemented as an RFID doggy door. This actuator can be a solenoid lock, a speaker, or even a web interface that logs data. I also show how to integrate an actuator, in this case an LED, to respond to a correct reading from the RFID module. In this tutorial, I go over how to integrate the RC522 RFID module with a Raspberry Pi board. The basic principles discussed lay the foundation to make an RFID doggy door. The purpose of this tutorial is show how to integrate an RFID reader and an actuator with a Raspberry Pi.
