Circuit Documentation

Summary

This circuit integrates various components to perform a set of functions that are not explicitly defined in the provided information. The circuit includes an Arduino UNO microcontroller, which serves as the central processing unit, interfacing with an HC-05 Bluetooth module, an HC-SR04 Ultrasonic Sensor, a L298N DC motor driver, and multiple DC motors. A solar panel and an NPF570 battery provide power, managed by a TP4056 charging module and a 24/12V buck converter. A rocker switch is used to control power flow to one of the motors.

Component List

Arduino UNO

• Microcontroller board based on the ATmega328P
