Circuit Documentation
Summary
This document provides a detailed overview of a circuit that includes an ESP32 microcontroller, a 5V mini water pump, a 12V power supply, a 5V relay, and a fan. The ESP32 controls the relay, which in turn controls the water pump and the fan. The power supply provides the necessary voltage for the components.
