Hello, fairly new to all this and I just need a suggestion for the last part of a project.
I am a high school teacher and I am working on a project to randomly pick a student in my class whenever needed. The idea is I hit a button and it randomly picks a student but appears like it is a spinner or roulette wheel. The desks are setup around the outside of the room so it is already similar to a wheel. So I'd like to have a larger light at each desk that lights up sequentially going around the room a few times really quickly and then slows down and stops at the selected student.
I've figured out the code and hardware part using an UNO, a few 74H595's, and a buzzer. Each desk would have a pin on the 74H595 and the buzzer for sound effects
Here is what I'm looking for some suggestions on:
- For each student workstation I need a way to mount some sort of LED/light and connect it to the board. It needs to be fairly durable and it would be nice if it was a little bigger that just a standard LED, something kind of flashy but won't be in the way when not in use.
- There is already cabling to the computers so adding more would be possible but doesn't seem that efficient. I know there might be some sort of way to use the PC but I haven't gotten into any of that yet and I would prefer something that didn't need the student to do something. Although it would be great if there was a not too hard way to have the computer in the pool automatically if somebody was logged into windows. So if there was something that could just autorun on login that may work.
