Circuit Documentation
Summary
This document provides a detailed overview of a circuit designed to control a water pump using a Raspberry Pi 4B, a MOSFET, a resistor, and a DC power source. The Raspberry Pi controls the MOSFET, which in turn switches the water pump on and off. The resistor is used to limit the current through the MOSFET. The DC power source provides the necessary power for the water pump.
