Library Installation

Before running this board you have to install the required libraries for RFID HAT.

For Python3, install these two libraries by running the below command on the terminal.

 sudo apt-get install python-smbus

 sudo apt-get install i2c-tools

Board TEST

Required Hardware

Raspberry Pi x 1
RFID HAT x 1

Enable I2C and Serial Interface

Open a terminal and run the following commands to enable I2C：

 sudo raspi-config

Choose Interfacing Options -> I2C ->yes

Again run below command to enable Serial

 sudo raspi-config

Choose Interfacing Options -> Serial -> No -> Yes
