Hey guys my Speedo broke and I've been thinking about using the VSS signal to move a stepper motor on the dial
I'm not sure whether the VSS is 12 or 5 volt but I'm not sure how to read it, could I just use a multi meter, and if it is 5v how do I read it in the Arduino, maybe some help with some example code for counting pulses a second from the VSS
What is "the VSS" signal? What device does it come from? Speedo in what vehicle?
Provide links to datasheets.
