First. I don't know where to start with this project so excuse the n00bness.
A little history: For those of you who have ridden in a BMW recently, they do a neat little trick with there door windows. Every time the door opens, the window lowers a little bit, when the door shuts again, the window raises back up to the shut position.
I would like to rig up something like this, hopefully using just straight hardware components (no software / logic) for my car. Reason being, it's a convertible and the windows catch on the top when they are all the way up and I open / close the door.
Of note: sure, I can mess around with adjusting the top for weeks, but there is nothing really wrong with the top. or the seals. And this is just so much cooler.
ANYWAY.
How would I: Build a circuit such that when the door opens (door switch goes high (+12V)) the window motor activates for say, .5 seconds in the down position (output 1) and then when the door closes (switch to 0V) the window motor activates in the up position (output 2) for 0.5s or 1s even.
In short: +12V outputs that can be activated for a variable length of time from either a high signal or low signal (12v signal).
Any ideas?
Thanks in advance,
Andy
