So I've read a ton of threads and I thought it was a simple job of connecting up GND and 12V and then you can read the RPM via the yellow wire.
After unsuccessfully trying to get a Arduino project to work, I eventually connected the yellow wire to my scope and don't see any movement - its 0V.
Its a DC Brushless 12V 0.18A Fan with yellow, red and black wires.
What gives? Am i missing something?
I've also tried pulling up to 5V via a 10k - still nothing.
