The kids at Church compete in Bible knowledge events every year, sometimes traveling to conventions out of state. This year, we had a lot of younger kids as the older ones had gone off to college, so we were staying at home and decided to have a "kids vs adults" competition.
I was tasked with making some game show styled buzzers for the event, based on a you tube video. How to make quiz game buttons - I Like to Make Stuff
I made the boxes, ordered the parts, then went off to sea. When I got back I had a week and a half of business trips to make, so I kind of ended up doing the electronics at the last minute. I wired up everything by the supplied wiring diagram, downloaded the code into the microprocessor, and nuthin'.
I spent all day yesterday un-wiring, checking every lead, and rewiring. As of 12:30 AM this morning, it still didn't work. I was ....unhappy. Sometimes you swing and you miss......
I was able to find an online quiz website that allowed the contestants to use their phones, an it was an acceptable solution, but the buttons would have been cooler.

. We ran a 60 question quiz with 4 teams and it worked pretty well. It is still a Beta version, so the reporting feature is a little clunky, but it saved my bacon and it was free.
For now, I have some beautiful boxes with push buttons, that maybe I can salvage and turn into something else if I can't get them working. The pictures below show the boxes (4 contestant and 1 reset box) and a look at the spaghetti wiring for the last breadboarding I did before quitting. I think there may be a problem with the code, but I have to play with the editor a little more before I am confident there! I will probably go "old school" and build a relay logic controller instead.
