First, let me just say I have no formal training with electronics and learn basically everything I know about it online, so please forgive my ignorance in advance.
Trying to add an inductive sensor to a small printer. Printer's mainboard, as I understand, accepts input voltages of 5v for endstop values (ramps based).
I have a 12v inductive probe, powered directly from a 12v external power supply (same as for heated bed). Since I had a couple of 7805's lying around,
and have used them in other projects to drop voltage to 5v, I assumed they would be fine to use in this instance.
The inductive sensor is a NPN sensor which is normally open.
Connecting directly to sensor's output gives me 12v via multimeter.
If I put the 7805 chip between the output signal of the probe and the multimeter, the output reading is 1.3v
I tested connecting the 7805 without the probe (directly from the 12v source) and it regulates to 5v.
Am I missing something here?
