hello forum! In my car, i have retro-fitted power window motors, which basically just "rotate" the old mechanical mechanism, from the inside of the door..
what i want to do now, is install some kind of "sensor" to be able to tell, if the window is rolled full up, or full down. I know that in cars, this is being done, by installing 2 mechanical switches, in the windows path, that when pressed, they ground the motor and stop the rotation..
But in my case this is very hard to be done, becouse in order to reach the actuall window, i have to un-screw and remove 2-3 sheets of metal...
so i was wandering, is there any easy (no MUC required) way to detect if the window is on a MAX position??
i have seen that you can generally detect motor stall, by back emf, but i dont know how i could use this in a "memory" way...
thanks!
