My son has to build a circuit that will allow a user to answer 15 multiple choice ( a, b, c, or d) questions. My knowledge of electronics dates back to High School (late 70's) but I'm willing to give it a try! Please help! (Previous entries include boards with 60 nails in them to which you touch a wire, I'm looking for something a little more sophisticated) We have one week and a $100 budget.
Thanks,
Tom (Canada eh!)
