rc522-iot-demo

A demonstration application that makes use of the rc522-iot API to interface with the mfrc522 RFID card reader and a Raspberry Pi Zero W

Requirements

This code requires you to install the Blynk python library and can be done by running the following command pip install blynk-library-python You also need to copy the rc522_iot API module into your working directory and then import the rc522_iot API module at the top of your script. It can be found and cloned here. It is also recommended that you make use of a python virtual environment before installing the libraries, by making use of tools such as venv or virtualenv.

Usage

To use the demonstration application you would need to do the following:

• Connect your Raspberry Pi and RFID card reader as described in Table 1
• Install the Blynk Android or iOS mobile application and create a new project
• Design your application as below:
  Blynk mobile application layout
• Configure the virtual pins of the application components as follows as described in Table 2
• Enter the authentication code sent to you by Blynk via email in line 8 of the .py script
• Run the rc522_iot.py file in your terminal to start the Blynk server
