Hi guys, I'm new to this whole deal, but I've got a decent background working with robotics, and i program computers + web sites. so I'm not totally lost. But I'm a bit lost here. I'm looking to segregate my tracks electrically, in a way that I can control which section of track is on, off,speed, and direction. My ultimate goal, is to hook this up to a computer via a serial port through something along the lines of a basic stamp (except not, because i hate PBasic, and I don't think basic stamps do PWM out... i may be wrong i hate working with parallex stuff) And be able to have sensors (most likely IR, but i might even go RFID just for the sake of learning RFID) along the track know when a train passes it, signalling which section of track the train is now in, and being able to "map" where trains are in the program, and keep track of the train through the track via programming that i'll do. The question is, has anyone tried anything like this before? And also, i'd need to know waht kind of current actualy flows on the rails, what voltage and amperage the trains need to run normally. Also, if anyone knows of any (multiple names for this) PWM controllers/speed controolers/motor controllers/drivers That would work in this application that would be awesome. I'm not sure if i made sense to anyone but myself, if i didn't, let me know i'll try explaining it differently! thanks a ton!
