I want to be able to trip a relay every time a line hits say 3VDC but I want to be able to change the voltage that it reacts to. Do I need to use a processor of some sort or is there a way to do this with resistors and pot's? It will be used in a car so I will need the relay to run off of a 12VDC line but react to a Throttle Position Sensor (TPS) that is 0V - 4.5VDC. I will need it to not pull any power from the TPS just use it as a tap to know when to flip the relay. What is the easiest way to accomplish this? I am mechanically capable and pretty good at soldering but I am not so good at designing, it has been at least 10 years since my digital/analog electronics classes in college.
Any Help would be greatly appreciated,
Dave
