hey guys, I am new to this thread, not necessarily circuits. I have took a clas in high school on this kinda stuff, but I forgot a lot of it. Now I'm starting a model train layout and I want to do something abnormal things to the layout (also saving some money) so here is my problem..... I want to make a circuit with a slow dc motor, a pot to change the speed of the motor, and a switch to change the dorection of the motor. Im using this for the turnouts. I have googled it, but haven't found anything, I don't even know if it can b done. Thanks for any help!!
