I've been the team coach for my school science competition team for just about 2 years now. Recently, I've started running weekly jeopardy nights for my students as I find that it is a fun and effective way to prepare everyone for upcoming competitions, while still keeping everyone engaged. This is when I began to think about developing a buzzer system for my students and I to use during these prep nights, as we lacked any sort of buzzing system to buzz ourselves in for our jeopardy games.
What it does
This system allows for students to buzz in to jeopardy questions on the fly, and when one team has already buzzed in, the system is locked out to other buzzers until the next question.
How we built it
We built it using an arduino uno, and various electronic components prototyped on a breadboard
Challenges we ran into
We had very rudimentary knowledge of electronic circuitry not to mention arduino coding, but we were able to pump this hack out within 12 hours thanks to our previous experience with C++ and digital logic.
Accomplishments that we're proud of
We're very proud of ending up with a hack that is practical in our lives, and of the fact that other people are going to be enjoying our hack as much as we enjoyed making it.
What we learned
We learned a heap about electronic circuit design through trial and error while learning to use our arduino to the fullest extent.
What's next for JeoParty
We will be custom designing and printing PCBs at our school's electronics lab in order to make our hack more permanent, and durable; as our hack is currently mounted on breadboards. We intend to keep working on this hack outside of the hackathon at our school.
