Now I can swap R-Pis and see if there is a problem with the car one.
swapped boards, and test rig ran the same, except that after analog left, left LED kept flickering and I couldn't stop it. Another software fault.
Also Red forward LED on at startup.

Problem installing Paho-mqtt. Need to look into it.
12/10/24 working through this. Got through the update of Setting up Python dependencies and installing MQTT Python Libraries
NOW! I remember, On boot I have to start the subscriber program. I'll look in a previous writeup and see if I described the process.
This goes quickly but gives instructions on how to enable the subscriber. and set the broker to run in the background.
