Quiz buzzer project kit (2116)

Two people (or two teams) can used the quiz buzzer to show who pressed their button first. When the button is pressed the buzzer sounds and either the red or green light is illuminated to show who was fastest.

This project is brilliant for demonstrating a wide range of electronics. It uses push to make & push to break switches, thyristors as latches, transistors, logic gates, LEDs & buzzers.

This kit contains:

  • 1 x 4081 quad 2 input AND gate IC
  • 1 x 4071 quad 2 input OR gate IC
  • 2 x 14 pin IC holders
  • 2 x push to make switches
  • 1 x push to break switch
  • 1 x 5mm red LED
  • 1 x 5mm green LED
  • 5 x 10Kohm resistors
  • 2 x 220ohm resistors
  • 2 x 2N5061 thyristors
  • 1 x BC547B NPN transistor
  • 1 x piezo buzzer
  • 1 x PP3 clip lead
  • 1 x 3AA battery holder
  • 1m connecting wire
  • 1 x quiz buzzer PCB

PCB dimensions: 59.5mm x 43mm.

Requires x3 AA batteries, available separately.

Hi, i am interested in making a quiz buzzer for an open day in work and your product seems to fit the bill, my electronics knowhow is limited having only put together simple circuits which are much like a paint by numbers kind of thing, if i was to purchase this product would you be able to supply the more detailed instructions that i myself would need? also would i be able to extend slightly the push switches so they would reach across 2 tables....maybe around 4 feet?
Many thanks, Lee.

Anyone that buys this kit will receive a set of instructions that include the step by step information for building the kit, debugging it and how it works. The more detailed notes that schools receive contain information on schemes of work, design brief work sheets and so on that are specific to using the kit in the class room and wouldn’t be of that much use outside of school. You can see what’s included in the notes by looking at the PDF which is in the above description.

As for the cable it wouldn’t be a problem to extend the switch cables or even put more than one switch in parallel.
