Failure, but maybe I can get it to work later...

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.

If anyone needs a free application for doing quizzes, surveys, or other voting type applications, you might want to give this website a try. QuizSocket. 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.

I don't know a thing about wiring ,Doug, but you did a nice job on the boxes. Maybe you can get it up and running and have them for a future event.

I'm with Herb. Anything electric, to me is magic. My suggestion is to get back to whoever made that utube video and see if they have an answer to your problem. However, I believe quite a few utubers watch a utube video, then make one of their own, based on what they saw.

I would have thought have everything wired together, and have some sort of way for the first buzzer (with a light), to cut off the rest of the buzzers. And I have not a clue how that would be possible, or even if it is possible. But if it is possible, that would be my first choice - simple as possible.

Just use a plain ol' flashlight battery and bulb. Should be easy to wire.

The goal is to have a lockout feature to only illuminate the first button pressed. It also was an excuse to play with these cheap, yet surprisingly capable micro controllers.

I have received a gracious offer from a forum member to help troubleshoot, as well as a link from another to a different wiring arrangement that may work.

Glad you understand, please post the outcome of this dilemma.

Doug the boxes look great and problem may be the controller program like you mentioned. I know a lot of things work great until they update the operating system and everything just stops working. Maybe it will be as simple as finding an update to the controller.

Good luck figuring out how to get them working, sounds like you have some help on the way.

Doug, It's amazing how things go adrift when you go to sea on a regular basis.

College tuition payments are almost upon me, then after that I can maybe find a 'normal' work schedule

A couple of things that I would check:

Test the voltage across the switches. With the switch not pressed it should be the supply voltage (5 volts?), pressed it should be 0.

Are your switches NO (Normally open)?
