I bought a one touch unit for the driver's window, only to find that it is down only and not particularly useful. What I want is up and down on both sides and while I'm at it, global closing would be nice.Global opening is great when returning to a car on a hot day but if the weather is like that then the hood will be down anyway. The car is a 1996 model so I ordered a relay module with four relays in which should fit in the existing box and now will need a bit of Arduinology dreaming up next week to implement the whole thing. Two presses on the lock should do global close if I can get a second closing pulse out of the system, one touch works by reading the switch and if it is thrown for less than half a second, it will run for as long as it takes to drop or raise the window fully, half a second or more and it will cut the power on release. Should be easy enough once I get around to it. I'll publish the code and circuit diagram once I have it working.
