@ Nick, sorry about the semicolon slip. It was late and I was tired. As for LEFT that is what I am assigning that output instead of say LED. My other outputs would be RIGHT, DOUBLE, and CAUTION and use a combination of pins as their outputs. My other inputs would be labeled SWITCHR, SWITCHD, and SWITCHC.
@michinyon I want the FETs on my two power driver boards to trigger at the same time. That gives me 4 input pins and 6 output pins with several free pins on my UNO.
