I would like to know if there is a way to hook 5v, 3 wire automotive sensors to an Arduino Uno to monitor oil pressure and temp sensors. I would like to try make my own computer monitor on a non computerized engine, anyone ever tried this?

Thank you
Doug

Presumably the 3 wires are 5V, ground an an analog signal?

Don't see why not, as long as you know or can analyse the output so you know what's going into the Arduino.

[irishAccent]Have you tried turning it off and on again?[/irishAccent]

Yes, would be 5v supply, ground and signal.

Thank you, Doug
