I got the Gertbot to work as a DCC controller, for trains and decoders, even programming of decoders works perfect.
Now i need a way to read on/off signals, as many as possible, for detection of trains on tracks or positions.
Since gertbot cant read the DCC feedback , i was thinking that i could do some analogue input somehow.
Im using a rpi2b and gertbot.
Im making controlling software in C++, for model railroads, and would love to have some kind of track detection , to go along with it.
Any good ideas ?
