Yes. I agree. That is why I was hoping for a coding solution for this. The idea is to announce to the user the actual pin they are using so there is no doubt they know what pins are being used. Its a calibration program for setting Servo's so there are no overcurrent problems. In calibration mode, I am telling them the Servo Pins and the Analog Pins for the controlling pots the servos are using. For new students, this is a double check for them to make sure their wiring is correct and also that they know for sure the variable declarations are correct. Once the servos are calibrated, and the variables are set, later we will be adding more analog items and want to keep track of them. We also want to use Uno's Nano's or Megas depending on how involved, how small, or how functional something needs to be.
I ran across this problem in doing that. I thought others might run into it so hoped someone had found this by now. Afterall, how many years has it been? So, I was surprised to find out there IS room to improve things. My hope is someone sees enough need to help solve this issue. There will always be changes that need to be made to wiring and even the software, but those are the cherished challenges many of us enjoy. Take this problem for example, who is having more fun than me right now? ;-/
