Circuit Documentation

Summary

The circuit in question is a complex system that integrates various sensors, actuators, and display modules with three Arduino UNO microcontrollers serving as the central processing units. The circuit is designed to monitor environmental parameters such as temperature, humidity, rain detection, and soil moisture, as well as to control actuators like motors and a servomotor. The system also includes a 0.96" OLED display and an LCD Display 16x4 I2C for user interface and data visualization. Power is supplied through solar panels and 12V batteries, with a toggle switch for on/off control.
