I'm working on a project and need some help with this circuit. I'm trying to connect a decimal-to-BCD encoder through a BCD to a 2 digit 7 segment display and have hit some snags. I've gotten the switches input into the decimal encoder. what type of power can be used with this? I've tried various forms of power supplies, but they don't work correctly.
