Take a look at the video to see it at work.
Check the next steps for the Schematic and code.
Step 1: The Schematic and Parts List.
Just connect it as the schematic shows. Upload the code and it should work.
I added a on/off switch a reset button and a power jack, those are not
shown on the schematic but easy to add.
To add a reset button just add a button to the reset pin, put one wire in the
reset pin and one in ground.
You can also add extra buttons for C and D as shown on the schematic.
My final project will have a red button for the red team and green for green team.
