Hi, i'm building an electronic quiz for my school project but i'm a little confused as to what to do.
I'm going to be making a quiz where there are questions displayed, and you have 2 levers for true and false. If you answer correct, green lights will flash (i'll be using 555 timers for that) and if you answer wrong red lights will flash. However I don't know how the machine will be able to know which questions are right and whitch ones are false (there are 10 questions that are going to be in order and they are labelled numerically so you have to do them in order). When you answer a question, you just remove it from the machine and go to the next one. How do i get the machine to recognize the answer to the question and display the correct lights? Is this anything related to programming chips or something? I'm confused
here is a pic of what i'm trying to do and a circuit diagram would be very very helpful, even if it's not detailed.
