I asked a similar question a few months ago about this. I have a 4 speed electronically controlled automatic transmission in my car. I want to make a box with 4 momentary buttons to select each gear. The car uses two solenoids (that require 12v) to shift the gears. The voltage from the solenoids must be applied throughout the whole gear, meaning that just a single 12 volt pulse to shift the gears will not work, the 12v needs to be applied the whole time. The gears are made using combinations of turning on two different shifting solenoids. With that said the gears go like this
1st gear: on on
2nd gearff on
3rd gearff off
4th gearn off
So those two solenoids just turn on and off to make the gears. The voltage fed to the solenoids is 12v. So what is the easiest way of making this with momentary buttons? I was told it can easily be done with relays, is this true? Also, I was told I can get everything I need to do this at radioshack. Does anybody have any ideas how I can build this? Thanks
