Magnetic Levitation with a Cheap Photosensor and the PIC Microcontroller

I made a magnetic levitation (maglev) machine. In this machine I used a photo interrupter as a position sensor. On the website, there are some examples of magnetic levitation machines in which Hall effect sensors are used. However, this type of machines is difficult to levitate for a long time because Hall effect sensors also detect electromagnets' magnetic field. But using the photo sensors makes easy for objects to levitate for a long time because photo sensors are not affected by magnetic field.

なるほど賢い！
非接触だとホール素子が要ると思ってました。

アナログのホールセンサーがあまり売っていないので、テンプレ通りにやるのも面白くないし別の方法を使いたいなと思ってやってみました
