Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes nMOS transistors, resistors, and an Arduino UNO microcontroller. The circuit is designed to control the gates of the nMOS transistors using the Arduino, with resistors connected to the gates for current limiting. The sources of the transistors are connected to the ground, and the drains are left unconnected in this configuration.
