HO Infrared Tachometer V2

New version of the tachometer, this time with TCRT5000 infrared sensors, which are more reliable than the TTP223 sensors of the first version.

The C++ code for the Arduino Nano is provided in a zip file: https://drive.google.com/file/d/1084oaeXQ9Y6hsn7CjCn6cscsfe5QcrWL/view?usp=sharing

The Arduino Nano board is the same as in version 1: https://cults3d.com/:4524661
The display panel is also the same.

The cabinet housing the infrared sensor is in three parts: a base that will be attached to the network tray with screws, the cabinet walls, and the roof. No gluing is required: everything fits together tightly.

There are two cabinet sizes: a thicker one and a narrower one (V2) to fit between two tracks.

The TRCT5000's operating indicators are located on the back of the cabinet using 1.8mm fiber optic cables (see the YouTube video for details).
