Hello, and thank you for letting me join. Really here to find out more about DCC++ as I am fascinated by PC control of a layout. Space is an issue for me [who doesn’t want more] so I have a small 10’ x 2’ end to end in OO gauge. Nevertheless I am keen to discover more about the Arduino based system. Now the downside. I have little to no idea about electronics or the Arduino so I will be seeking more answers than I can contribute. So, if you’ll indulge me I’ll try to keep the questions sensible, minimal and hopefully memorable [to me]. Image shows one end of my layout - under construction. R-
