This here is a binary counter. With a simple flip of a switch, it will count to 15! Just think of all the amazing things you could do with the numbers between 0-15.

I made this with the intention to give newer players and people trying to get into redstone an example to learn from. You can directly download the schematic file, look at the pretty pictures, or play in my world to see this counter in action.

I always suggest players trying to learn redstone visit this page on the Minecraft wiki about Redstone Circuits, for a break down of all the gates for redstone.

As long as this helps one person I'll be happy.
