Hey guys
I'm currently brainstorming on how to build a circuit for a school project. Basically we've built a model city on a huge board. Let's say as big as an average chalkboard or whiteboard in school.
The board is filled with a two rows of LED's, so that's a huge number of LED's. The gist of our experiment is that when someone types in a certain number let's say 1234, the LED's light up. So if 1234 is written LED's will light up low. However if 5678 is typed then the LED's shine bright. Basically there are only gonna be like 3 or 4 number combinations that are going to be allowed to type in. So dim, medium, bright and very bright.
Any ideas how this can be accomplished?
I was recommended to use a microprocessor? Any recommendations which one? Cost efficiency is something I am considering.
So if I use a microprocessor will I still have to use a laptop for someone to type the numbers in from?
