My daughter and I are working with your Dual Axis Solar Tracker, but the vertical movement is opposite of what we expect. In other words, when we move a light from the base toward the top of the unit, we would expect it to pan up to stay with the light. It doesn’t. I pans down–away from the light source. We have triple checked the wiring, we have re-homed many times (following the directions from your site), we have verified that the code looks correct.
Does anyone have other suggestions for how to troubleshoot this issue?
