    Hi, I'm new to this forum, but I've been working with electronics for a little while. I'm trying to build a circuit that can vary voltage output based on a mechanical movement. It will have 12V input with approx. 18A, and I need to vary the output from 0 to 12V evenly throughout the range based on the mechanical movement (using a pot maybe?). I've been looking at using PWM, but I'm still unsure on how to proceed. I'm also unsure how to handle the large amount of current. I've researched a little but haven't found exactly what I'm looking for. Any help would be great!

    Hi and welcome to Electronics Point :)

    It would really help if you explained more about this project. What's the purpose? What will the input be coming from? What will the output be going to? Any relevant diagrams or photos would be helpful too.
