hi there,
I`m dealing with a dc motor to do some task. To make my explaination easier, the task is something similar to the power window for car, that is to lift the window up untill fully closed.
My question is that, how can I design a circuit to cut the current ( by simply activating a relay) supply to the dc motor when it is fully closed? is there anyway to measure the current flow that supply the current to the dc motor , just like the circuit of the power window of a car that is stop the current flow when it is already fully closed?
thanks alot.and by the way im dealing with a 12v dc.
