Two people (or two teams) can use 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.

Features:

  • Audio and visual indicator.
  • Demonstrates a wide range of electronics.

    A:

    Hello Chris, The easiest way to do this might be to replace the original LED’s with high brightness LED, and then encase these in a small transparent enclosure. This should make it more obvious who has buzzed first. You should even be able to place the LED’s that come with the kit in an enclosure to make it more obvious.

    A: Unfortunately it would take a different circuit to do that. There's not a simple way to connect two of these kits together to achieve what you're after.

    A: Put the LDRs into where R1 and R5 are marked on the PCB Put the two resistors R1 and R5 into the slots where the switches should go. You might need to experiment with the values of R1 and R5 the resistors to get the sensitivity you require.

    A: You can with solder mop and solder suckers if you are careful. Each time you do this though you risk taking a pad off the board and each time the PCB will get messier. If you are really careful and have a lot of experience you might damage 1 in 10 kits. If you haven't done much soldering before you might damage 1 in 3 or more. You can probably re-use some kits this way but i wouldn't say the kits are re-usable as they weren't designed with that in mind.

    A: The maximum allowable length of cable would depend on the resistance of the cable. If you have a data sheet for the cable you are using I could work it out for you. That said, 10 feet should be fine for most cable types.

    A: 9V would destroy the LEDs and upset the logic on the PICs as all the resistor values would need to change.

    A: 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.
