Hello! Im new to the EEVBlog Forums and I need help with a project.
Im working on a model train layout and want to make my own DCC system. Except, my layout is small and so is my budget, so having a proper DCC layout is not a good choice for me.
So thinking, I have a good and young mind, I can surely make something in place of DCC with arduinos! And I was correct; but realizing that there is only two rails (One for ground and the Other for signal) I need to give power over the rails. I've seen this done before, but they seem to only run at 5v or so. I need to use a transistor or something to increase that to 12v to power the old dc motor for PWM. I've got that bit working but If anyone could, please give me a schematic to follow. I've tried something already and ended up blowing out an arduino nano.
All help is appreciated!
