It became necessary to create a filament counter for your 3d printer. I have independently developed models of parts for you. I also independently wrote a program for Arduino in the XOD environment. During the writing of the program, I created a new multiplication node. I used the hall sensor and the ssd1306 LED display on the i2c bus .
If necessary, I will fill in the source files.
