So I am messing with a PC fan and the RPM sensor, I might want to use it for a propeller clock project.
I am powering the PC fan with my bench top power supply at 12V. I placed my scope probe on the RPM sensor pin
And I get this.
What are those spikes? How can I eliminate them?
From what I read, you need to pull that senor pin high but it looks like that is not the case.
