Hey guys,
Please bare with my ignorance, but I have been searching for an easy to make circuit for something I am working on, but I have had no real luck finding a good explanation on how it works, or a good schematic. Here is what I got.
I have a 12V DC motor. I have cross-wired a DPDT toggle switch so I can reverse the motor. What I need is a circuit that will have a variable time delay before the motor starts running in the opposite direction. I have a 10K potentiometer that I would like to use as the time delay. I am shooting for 15-20 seconds of power off time before the motor starts again. I would like to have a 0-60 second time delay but I can work that out when I understand this circuit better. I have a few 555 chips and a box full of components. I have read that the chip is safe running at 12v, but I am not sure how the circuit would work or look once the current is reversed. Can someone help me to understand? Thanks in advance.
