Quiz Control Panel

The Quiz Control Panel is the standard setup of four contestant buttons, each with an output to provide an indication of who pressed first. The program locks out the other three buttons and provides an output for a 1s buzzer. The Question Master then has to press his reset button to normalise the system. A GUI with different team colours is included if a monitor is used. For when the Pi is headless (no monitor) I have included a button to gracefully shutdown the Raspberry Pi so it can be unplugged without fear of corrupting the SD card. Of course the program will need to be started at power on, this is done by editing the file:

sudo nano /home/pi/.config/lxsession/LXDE-pi/autostart

and adding the line,

@/usr/bin/python /home/pi/Quiz.py (the path & program and the path & file name of the script)

The Quiz buttons, lamps and buzzer are currently being built, I'll update when they are ready.

RPi Quiz Script (just copy & past into IDLE 2.7).
