Introduction: Quiz Box 2.0

Create an RFID secured Quiz Box that can print out questions to an LCD and read the answers using a 4x4 membrane switch, giving instant feed back using an LED.

Step 1: Hardware Requirements

Hardware Components
1 Arduino Uno R3

1 Raspberry Pi

1 4x4 Membrane Switch keypad

1 RGB LED

1 1602A 16*2 Lines LCD Module

1 RFID reader

2 RFID cards/dongles

Plenty of Female to Female or Female to Male wires

Step 2: Install Librarys

Serial #used to communicate from the Arduino to the Raspberry Pi over USB cable
Time #used to create delays so different things can be displayed on the LCD for different durations

Pad4pi #Used to retrieve input from the keypad to the Pi

https://pypi.python.org/pypi/pad4pi/1.0.0

LCD display #used display characters on the LCD module

Step 3: Wire Your Hardware Togather

Step 4: Design Your Arduino Code

Observe the attached Arduino code

Decide if you want the output to in Dec or Hex

Decide if you want to know if an RFID has been scanned more than once

Edit the code accordingly

If you are only looking to exactly replicate the Quiz Box 2.0 always output the Dec number when an RFID is scanned

Step 5: Write Your Code

Here is our code in python
