Rotary encoder with gear tooth sensor was created by Dinuka_Shehan
Can we use gear tooth sensor/s to make a rotary/quadrature rotary encoder?
For A and B phases.

you'll need some wire.

No need to add resistors to output pin to 5V as pull up resistor?
Or direct wiring without any components?

Depends on what you are wiring it to: some parallel ports have pullups, most do not, so you would need one. Also some BOB's do have some do not.
Measure the input pin to GND, if it has 3.3V or 5V, you do not need anything.

Just remember reading these (or any encoder) will be limited to speeds with pulse widths wider than your base-thread.
