PNP Sensor Hookup

Correct it is 12v coming back from the sensor.

Should I just bypass the voltage divider and use multiple 2.2K resistors.

A single resistor has the voltage toggle between 2v and 6v, if I add another shouldnt it reduce even fruther below the 5v. In reading FIXED (Thanks): Arduino nano.. voltage divider not working. - Project Guidance - Arduino Forum this guy had an issue with his volatge divider.

I just dont understand why a multimeter is able to show the voltage change but I can't see this on my Arduino
