Hi: I'm running my trains using a DCC++ implementation running on an Arduino Mega. I built a panel with 4 throttles (sliding pots) and switches for controlling the turnouts. I will add a section to my layout and it would be convenient to command the locos from another panel. Is it possible to connect another Arduino sending its DCC signals to an already running DC layout? Thanks
Not really, unless the 2 sections are completely isolated from each other. There's no way for the DCC++ to synchronize the DCC signal from 2 separate systems. What you should do is add more of your throttles externally, and connect them to the primary DCC++ system, so it will generate the DCC signal from both panels. If I remember correctly, your setup probably would require a significant amount of work to accomplish what you want.....GOOD LUCK.
