After building jig #2 I discovered that the 60 arms are not "built to specs." So need to rethink the process.
Added a spam trap to the domain. Will start adding links to the front page, etc.
REF: IR Sensors. Adjusting the sensors so ambient changes do not trigger the sensor has not been satisfying. So turning the logic around and using ambient light to hold the sensor "on" and the loco shadow to turn the sensor 'off." May need to cover some of the IR LEDs. Need to adjust all 36 sensors and change the DCC++ Base Station.
Working on the software for raspberry Pi 3 (3A) to debounce and delay the low-to-high change to match delay in the turnouts.
