1. The problem statement, all variables and given/known data We can't use anything else, and just have to make a logic circuit (either OR, AND or NOT) with just this material. We can use less or more diodes but I have only 5. 2. Relevant equations 3. The attempt at a solution I tried setting it up like doides but no help at all. I thought LEDs would function same as diodes but it didn't.
