Jeopardy-style game show buzzer?

I need a Jeopardy game show buzzer setup.

My friend made it through the selection process, and can be called anytime in the next 18 months.

He found one online for $275, but he asked me if it’s possible to build one.

I’ve actually got push buttons for timing track and field. (Or is it like an industrial e-stop button with a mushroom head on the table?)

I just need the circuit to select and display the first button press.

I’m sure I can design something, but why reinvent the wheel?

If anyone has been through this or can offer some advice, I’d really appreciate it.

I’d love to add a little LCD or OLED screen to show how much the second and third presses missed (like in milliseconds).



It sounds like an easy Arduino project. Inputs for the switches and outputs for lights to indicate the winner. There are lots of LCD and LED displays available for Arduinos.

Here are a few of the links that turned up from a search for Arduino jeopardy buzzer:
