Hi. I'm trying to make a circuit to power a motorised screen for the car. the screen first comes out the dash horizontally and then flips up. Al teh mechanism (gears + motors) are already there, I just need a circuit to power them. I've been told I can do it with relays (no PIC required).
I really don't know hwere to start though. I need the horizontal motor to move the screen out until a switch is pressed (screen is fully extended), and hten i want the flip motor to turn on for a certain number of seconds (this doesn't have to be too accurate becuase I'm gonna have buttons to move the angle as welll for sunlight).
Then when i press another button the flip motor folds the screen down (i.e. rotates the opposite way) until a switch is press, and then the horizontal motor starts (the opposite direction) and moves the screen back in until another switch is press.
Any help is appreciated.
