The light bulb comes on

I spent the last three days wiring up a panel for my main yard. I have 37 buttons and 39 lights to connect to my computer I/O. When I finally get near the end it hits me, the computer I/O only has 32 connections for buttons and lights! DUH! And the light bulb comes on.
Now I have to find places to connect for the leftovers. It sure is great when a plan comes together. The good news is I can start testing this panel tomorrow.
