Hello kind people, I need some help/information on a few things.
I need an adjustable timer relay for a 12v system, so that when i close the doors on my car and press the lock button the relay will put power to the windows so that they close. So in theory the relay will have 5 pins, 12v+, a ground, one to disable the relay, one where the trigger wire will connect and an output that will stay live for around 10 seconds.
You don't even have the relays? Man, you got some research on your hands. Try Digikey.com. A one shot is probably the simplest way to do it. It's just a 14 pin chip with a capacitor & a resistor. No biggy. Go to Radio Shack and pick up some proto-board and hand wire it.
What sort of resistors and capacitors will i need?
I'm sorry for sounding dumb. The only electrical things i've done before is wiring a few alarm systems in cars. So you may have to bare with me a little bit.
Also can anybody help me with the LS7220 Circuit. What exactly will i need to build it? I have an LS7220 ordered and a keypad.
