Circuit Documentation

Summary

This circuit appears to be designed to monitor magnetic fields using multiple Hall sensors and control a series of solenoids accordingly. The Arduino UNO microcontroller is used to process the signals from the Hall sensors and drive the solenoids through MOSFETs. The circuit includes protective diodes for the solenoids, resistors for current limiting, and an LED for indication purposes. A 12V battery provides the power source for the solenoids, while the Arduino is powered by its 5V pin.
