Crowtail- MPU6050 Accelerometer & Gyro


A Crowtail- MPU6050 Accelerometer &Gyro which has 3-Axis digital accelerometer and 3-Axis gyroscope,and a Digital Motion Processor hardware accelerator engine with an auxiliary I2C port that interfaces to 3 party digital sensors such as magnetometers. It’s the first motion processing solution projects and it can apply on game controllers, motion controls, Four - axis aircraft and other consumer devices. The MPU-60X0 is a 2nd generation motion processor and is compatible with the MPU-30X0.

Model: CRT02122G

A5(J7) SCL


STEP 1.Download program
STEP 2 Configure controller board&communication port
On top of the Arduino IDE, click “Tools>Board>” and select “Arduino Uno” from the available options
Select the COM port that indicates Arduino Uno. Please note that the actual numbers after the “COM” word will vary from computer to computer, so they could be different from the ones shown in the figure.

STEP 3 Install Library: Unzip the file and copy it to the Libraries directory under the Arduino installation directory MPU Libraries.jpg
STEP4 Open Arduino IDE and load MPU6050_raw.ino:click "File→Examples→MPU6050→Examples→MPU6050_raw.ino"

// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation
// is used in I2Cdev.h
#include "Wire.h"

// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files
// for both classes must be in the include path of your project
#include "I2Cdev.h"
#include "MPU6050.h"

// class default I2C address is 0x68
// specific I2C addresses may be passed as a parameter here
// AD0 low = 0x68 (default for InvenSense evaluation board)
// AD0 high = 0x69
MPU6050 accelgyro;

int16_t ax, ay, az;
int16_t gx, gy, gz;

#define LED_PIN 13
bool blinkState = false;

void setup() {
    // join I2C bus (I2Cdev library doesn't do this automatically)

    // initialize serial communication
    // (38400 chosen because it works as well at 8MHz as it does at 16MHz, but
    // it's really up to you depending on your project)

    // initialize device
    Serial.println("Initializing I2C devices...");

    // verify connection
    Serial.println("Testing device connections...");
    Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed");

    // configure Arduino LED for
    pinMode(LED_PIN, OUTPUT);

void loop() {
    // read raw accel/gyro measurements from device
    accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

    // these methods (and a few others) are also available
    //accelgyro.getAcceleration(&ax, &ay, &az);
    //accelgyro.getRotation(&gx, &gy, &gz);

    // display tab-separated accel/gyro x/y/z values
    Serial.print(ax); Serial.print("\t");
    Serial.print(ay); Serial.print("\t");
    Serial.print(az); Serial.print("\t");
    Serial.print(gx); Serial.print("\t");
    Serial.print(gy); Serial.print("\t");

    // blink LED to indicate activity
    blinkState = !blinkState;
    digitalWrite(LED_PIN, blinkState);

STEP5 Click the Upload.png to upload the code to the Crowduino board
STEP6 After the program is downloaded, open the Serial port monitor of Arduino IDE, set baud rate to 38400, turn the sensor, and the printed value will change, as shown in the figure
