The circuit in question is designed to interface an Arduino UNO with a variety of components including a RAIN SENSOR, a DC worm gear motor controlled by a Motor Driver, an RFID-RC522 module for RFID communication, a 12V 200Ah Battery for power supply, a solar panel with an MPPT SCC (Maximum Power Point Tracking Solar Charge Controller) for energy harvesting, a copper coil, and a Power Inverter for converting DC to AC power. A buck converter is also included to step down the voltage for certain components. The Arduino UNO serves as the central processing unit, managing sensor inputs, controlling the motor, and communicating with the RFID module.
