Up/down issue remains and is on and off. Looking for loose connection.
Adjusted the sensitive of two IR sensors and repaired/replaced another IR plug.
With the track down I turned on the work lights and discovered that the LEDs may be IR, but the receivers have a broader range. Half the sensors went active! Now I understand most of the "wiring" problems ~ Got to work on lighting.
Added 5v0dc to the Arduino MAGA instead of drawing power over the USB. Seems to make the USB interface more stable now and will be better when the USB is connected to the Raspberry Pi
