Circuit Documentation

Summary

The circuit in question is designed to interface an Arduino UNO with an MPU-6050 accelerometer/gyroscope module, an HC-SR04 ultrasonic distance sensor, and a buzzer. The Arduino UNO serves as the central processing unit, controlling the sensor inputs and outputs. The MPU-6050 is connected via I2C to the Arduino for motion tracking, while the HC-SR04 is used for distance measurements. The buzzer is controlled by the Arduino to provide audio feedback based on sensor readings or other logic.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Purpose: Acts as the central controller for the circuit, interfacing with sensors and providing outputs.

MPU-6050

• Description: A motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer.
• Purpose: Provides motion tracking capabilities to the circuit.

HC-SR04 Ultrasonic Distance Sensor (Wokwi Compatible)

• Description: An ultrasonic ranging module that provides 2cm to 400cm non-contact measurement functionality.
• Purpose: Measures distances to objects and provides this information to the Arduino.

Buzzer

• Description: An electromechanical component that produces sound.
• Purpose: Provides audio feedback based on sensor inputs or other conditions defined in the code.
