Circuit Documentation
Summary
The circuit in question is designed to control various devices such as fans, a water pump, a heating element, and to monitor temperature using a DS18B20 sensor. It includes selectors for manual and automatic control, a buzzer for alerts, and an LCD I2C display for user interface. The core of the control system is an Arduino UNO microcontroller, which interfaces with a 6-relay module to control the connected devices. The circuit is powered by a 12V 5A power supply, and the Arduino UNO is responsible for the logic control and sensor data processing.
