Hi, New to DCC and have built the layout below. I have placed some sensors on the layout but not on actual board yet in entries of sidings and at the end as a stop sensor. My goal is to be able to send a loco from one location to another or just run around for a few circuits and at a later date be able to monitor which loco is exactly where on my layout at any given time. I am using an Arduino Mega so have quite a few digital and analogue inputs as well as outputs for turnouts. I was wondering if anyone can advise me if these are correct positions and also where else I should place them please? Thanks in advance for any suggestions.
