    Hey, I've managed to get this thermistor controlled fan to work on circuit wizard but I cant seem to make it on a breadboard. The motor is a 6v motor and turns on at 23 degrees. Is there anyone who could please create it on a breadboard take a picture and show me how to wire it up? I will be so grateful. I've got to help one of my students and I just can't do it. I'm getting very worried as it is for their exams. Please help!

    The NPN Darlington Pair is for?

    Move the transistors to switching the ground side of the motor for a start.

    See This Relay switch for concept
