Ok sounds good. DO I need 12volts? I was planning to use 5. I will probably need to debounce 3 switches. 2 inputs and reset.
I am going to use a transformer I found at radioshack for my power supply. It ouputs 6 and 12 volts. I will use a 7805 voltage regulator to drop that to 5. Should I get a pos. voltage reg or a neg. regulator. What is the difference?
