Hi All,
Before i go too far down this route, i was wondering of it was possible to expand on my project that already works.
Currently I have and Arduino mega controlling points (turnouts), isolation sections and night scenes via relays and position indicators leds on a model railway. There is currently a Bluetooth connection between two of the baseboards of the railway. for simple communication - i.e. it sends a single character to the second board, and the points change depending on the character sent (a,b,c...etc.)
I would like to extend this to other baseboards, but obviously Bluetooth is a 1-2-1 commutation. I was therefore thinking wifi to broadcast serial commands network wide. I have a wemos mega, NodeMCU ESP8266 and D1 and will get extra d1's or nodeNodeMCU ESP8266's if needed for the railway, which is why i am looking at it being expandable.
I would also like to be able to put some of the control on a webpage, simple indication and control.
before i go too far down this route, is it actually possible to do this?
Many thanks for your time
