Hey guys! So some of you know I've recently taken control of my university's anime club. In April, we usually do a Jeoparody panel at the local convention. To answer questions, we just use the hand method, whoever raises their hands first gets to answer the question, but when there's 9 or 10 participants and they all raise their hand at the same time, it's really hard to know who to choose.
So for next year, I wanted to make a set of 9 or 10 buzzers. I was considering modding the Staples easy button (or similar) to transmit to my computer, and from my computer I'll be able to see who pressed first. I could also set the time when the buttons can be pressed from my computer, so no one presses early. It'd also be cool to set a sound for each buzzer, for comedy.
Only I'm not sure how. Would bluetooth be the best communications means? I think I'd be better off programming my own PIC rather than getting 10 Arduinos, since they're much cheaper and I have the means to interface them myself. I'm also not sure about the program so I can interact with the buzzers through my computer. Any ideas?
