Summary

This document provides a detailed overview of a circuit that integrates an MPU-6050 accelerometer and gyroscope sensor with an Arduino UNO microcontroller. The MPU-6050 is used to capture motion data, which is then processed and output by the Arduino UNO.

Component List

MPU-6050

• Description: The MPU-6050 is a 6-axis motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer.
• Pins: VCC, GND, SCL, SDA, XDA, XCL, AD0, INT
• Purpose in Circuit: To capture motion data (acceleration and gyroscopic data).

Arduino UNO

• Description: The Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.

#include "Wire.h"

  //pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
  mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
  data.X = map(ax, -17000, 17000, 0, 255 ); // X axis data
  data.Y = map(ay, -17000, 17000, 0, 255); 
  data.Z = map(az, -17000, 17000, 0, 255);  // Y axis data
  delay(500);
  Serial.print("Axis X = ");
  Serial.print(data.X);
}

This code initializes the MPU-6050 sensor and reads the accelerometer and gyroscope data. The data is then mapped to a range of 0 to 255 and printed to the serial monitor. The setup() function initializes the serial communication and the MPU-6050 sensor, while the loop() function continuously reads the sensor data and outputs it.
