Quiz Buzzer 3D – Level up your family games!

This funny little project helps to clarify the most important question: Who was first? With real quiz buzzer features, like:

• First answer locks the other buzzers
• Indication of fastest buzzer - with light and sound effects
• Easy unlocking by Player 1 (double-click releases the buzzers)

The project is easy to print without support and no screws needed! All components (Arduino Nano, Buzzer, Lids) can be snapped into place.

Material list for the assembly:

• Arduino Nano
• Arcade Buttons, 60mm https://a.aliexpress.com/_EIQ4OMy
• Passive Buzzers https://www.amazon.de/dp/B07ZTR24HX 
• 4-core Cable https://www.amazon.de/dp/B0CWLS99PG   
• Crimping Set (Optional, can also be soldered directly)
• Soldering Iron
• Hot-Glue

For assembly instructions please see pictures. I use the hot glue to fix the cables within the buzzers/Controller and to fix the dupont connectors (to avoid a slide out). Schematic & Arduino sketch is attached to download. Hint: The Arcade Buttons LED do not need a separate resistor and can be connected directly to the Arduino Nano (+ and GND directly to the LED).

Happy family time with this print!
