Hey, I'm newto trying to step up and down voltages but i know what i want to do, so hopefully someone can help
i'm going to be getting a motoral 3bar map sensor (forget digikey part #)
but the map sensor has a 5.1v input and 4.9v output
what i want to do is go from 12v dc (automotive) to the 5.1v input of map sensor hooked up to a vacuum line that gives a varying output of -4.9 - +4.9
I want the map sensor to control a 12v lamp connected to it. Kind of like using the map sensor as a dimmer for the lamp
the lamp is .24 Amps (2.88 watts) but i may end up w/ a larger lamp with a high amperage rating.
is there a way (and how) to increase the +/-4.9 to 0.0 - 12.0 volts?
and have the ability to add more or larger lights to this circuit?
thanks
