Let's try mendel auto bed leveling with a PNP inductive sensor (No.1)

PNPinductiveセンサースイッチ（LJ12A3-4-Z/BY）を購入したので、Auto Bed Levelingに挑戦。
今回は、5Vの入力電圧でごまかしながら使う方法をとる。利点は、配線が比較的簡潔。欠点は、sensing distanceが短い、スイッチが不安定かも。

では、はじめに、10k-ohmの抵抗（10kで多分大丈夫？）をセンサーの２つライン間（黒と青のライン）にハンダ付けする。

This is the sensor I bought.
Soldering the resistor between the two sensor wires.

I bought a PNP inductive sensor (LJ2A3-4-Z/BY). So let's build the auto bed leveling using this sensor. At this time, I am going to use the voltage with 5V not 12V for this. The advantage of doing so is a simple wiring. But the other hand the sensing distance will be reduced and the switching might be unsteady sometime. Well, anyway.

First thing to do is soldering 10k ohm resistor between the two wires of sensor (black and blue). That's it!
