Jeopardy style games are popular for their ability to create excitement and to be a learning aid at the same time. One initial problem when thinking of setting up a Jeopardy game is "What to use to know who answers first."
We made our first DIY electronic "voting" or "first to respond" circuit about ten yeas ago. A director of a summer camp wanted a new setup, and it seemed to be the perfect opportunity to update the design and perhaps use an Arduino controller for implementing the logic.
After a few hours of perusing the web for updated ideas, we purchased the "Lights and Sounds Buzzers" by Learning Resources for evaluation as the buttons. We used an Arduino to implement the "first to respond" logic and control the lights/buzzers and LEDs.
This design also keeps track of the order in the cases where multiple teams hit their button, so 1st, 2nd, 3rd, and 4th place is known.
We were pleased with the end result and it was enthusiastically received by the summer camp director and counselsors. We'll see how it holds up in it's first "field test" in a few weeks.
The links to the right provide more details on parts, modifications, and code.
This was a fun project. Best wishes in your search for the "perfect" Game Quiz controller.
