Hi! I just made an account here because I've been tinkering around with Arduino and circuitry for a while and finally sat down to take it seriously. Yesterday I made this 'elevator' that raises and lowers a tupperware outside my dorms window... for fun.. I wanted to add a speed control and based on my limited knowledge I thought a linear taper potentiometer would do it, by slowly increasing resistance on the current running to the motors, the speed should decrease. My circuit looks like this:
The behavior of my circuit that results from this is that the motors run on full power only when the pot is fully on, as in the wiper in the pot is touching the lead pin, fully connected(turned all the way left in the photo). Turning the pot even the slightest degree to the right, i.e adding any resistance, turns the motors off... why? I have no formal training in electrical engineering, but I am savvy and do know some... Help!1!1!
