Hello all. It seems like this should be pretty easy to do but I’m obviously missing something. I’d like to use a PWM Relay Switch like this: https://hobbyking.com/en_us/turnigy-tx-controlled-relay-switch.html to operate a simple laser scaler via the gamepad - idealy using a shift/button combination just to turn the scaler on and off . The physical portion of the project is no problem and mostly done. Would anyone be willing to walk me thru the ArduSub/QGC setup?
