The idea is to have a portable RFID reader that will display the tag output. This will also server as a starting point for later projects such as a read and write option with number pad.
many, many wires
Step 1: RFID
First thing we do is start wiring up the power to the RFID and the breadboard.
Step 2: LCD and Potentiometer
Next we wire up the power to the LCD and the potentiometer.
Step 3: Wiring the LCD
Then we wire the LCD screen to the Arduino
Step 4: LCD to Potentiometer
A small but important step is wiring the potentiometer to the LCD to adjust brightness.
Step 5: RFID
Finally we wire up the RFID to the Arduino. Source included.
