Minecraft Logic Gates
I finally got around how red stone works and decided to make some logic gates. I made AND, OR, NOT, NAND, NOR. This should help you make the gates yourself.
Oh and btw "OR WITHOUT LAMP" and "OR WITH LAMP" is the same. That's why I didn't demonstrate the one without lamp. I put it in there just to show how easy OR gates can be.
