Thanks so much for doing that! Learning arduino is something I’d definitely like to do some day, but it probably won’t be for quite awhile. In the mean time, I just found a couple of these dual relays for $10 each on eBay. They’re exactly what I needed. With the transmitter switch in the center position, both relays are open. Throw the switch in one direction and one relay closes. Throw the switch in the opposite direction and the other relay closes. Thanks again!!
