Quiz Machine Controller

Probably a bit of an over-kill this one but if you’re after spot-on accuracy for determining which contender pressed their buzzer first then the FPGA on the PiXi could do that… After that it’s up to the Raspberry Pi to create some wacky sounds to indicate who hit their buzzer first…

Take it a step further and use the internal I2C switch to create 4, 6, 10, 12… extensions to the I2C port on the Pi and use an I2C interface to add more buttons or functions to each contestant’s keypad.
