Statement from Ixion Model Railways Ltd
We (2 club members) are constructing an n-scale layout, a 7.5 scale mile folded dogbone with continuous running, a lower deck with staging (complete) and an upper deck for some switching interest (in progress).
We use Digitrax, JMRI, Arduinos and servos for switch motor control. Currently the layout is operating as a loop and we can run 4 or more trains at a time. Switch control is done with JMRI running on a Rasp-pi 4 or Digitrax switch commands from controllers. Since there is only 2 of us now, one has to constantly go to the computer to throw switches (control from the controllers is awkward at best at least for us, can't remember the switch numbers).
The Arduinos we use are an ATMega 2560 to get block sensor data back to JMRI and 2 Pro Minis to control the switch servos. All sketches were provided by Dr. Geoff Bunza and with modifications for this layout are working perfectly.
Here is what we are aming for and need help accomplishing. We want to add manual switch control (remote panels) to the Arduinos to allow both of us to run trains with feed back to JMRI to keep in sync, to keep the panels updated properly.
Hardware is not a problem for us, its the programming to accomplish this. I have a general understanding of programming but loose it if it gets to complicated. I can muddle my way through a simple program but when multiple libraries are included I can only assume they work well.
