In this video lesson I show you how you can measure rotational velocity using the gyroscopes on the MPU6050 IMU module on the GY-87 board.

Below is the code which we develop in this lesson.

#include <Adafruit_Sensor.h>
#include <Wire.h>
float Ax;
float Ay;
float Az;

float Gx;
float Gy;
float Gz;

// If You want Calibrated results, you must rotate
// your board to all possible orientations, and
// record your velues of xMax, xMin, yMax, yMin
// zMax, zMin. I show you how to do that in LESSON
// 79 on my youtube channel. Put in your values and then
// uncomment the code below. Don't use my values, you have
// to measure your own for it to work.

// float xMax= 1.03;
// float xMin= -.97;
// float yMax= .98;
// float yMin= -1.01;
// float zMax=.96 ;
// float zMin= -1.08;

// float xOffset = (xMax+xMin)/2;
// float yOffset = (yMax+yMin)/2;
// float zOffset = (zMax+zMin)/2;

In this video lesson we show you how to take the calibrated accelerometer data from the MPU6050 and use it to calculate the tilt of the board. We can calculate tilt in two axis, or the roll and the pitch. This is the schematic for the project:

Using Arduino to Calibrate the MPU6050 Accelerometers

July 31, 2025 admin

In this video lesson we show you how to calibrate the accelerometers on the MPU6050. You will have to find the min and max accelerometer numbers for your particular board, but I show you how in the video. Below, we show the schematic of how our circuit is connected.

In the lesson we developed the following code. Measure your min and max values of the three accelerometers according to the instructions in the video. Then enter those numbers in the code below, and un-comment out the commented lines. If you run the code as-is below, it should work, but the results will be uncalibrated and not as accurate as possible.

Measure 3 Axis Acceleration on an Arduino with the MPU6050 IMU

July 24, 2025 admin

In this video tutorial we show how the MPU6050 can be used to measure acceleration in the x, y, and z directions, that is, Ax, Ay, and Az. We also introduce the idea of plotting the data to the Arduino Serial Plotter to make visualization of the data easier.

Below is the schematic we are using to access the MPU6050 on the GY-87 module.

Below is the code which we developed in the lesson to measure acceleration in all three axis.

#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>
#include <Wire.h>
float Ax;
float Ay;
float Az;

Adafruit_MPU6050 mpu;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  mpu.begin();
  Serial.println("MPU6050 Started!");
  mpu.setAccelerometerRange(MPU6050_RANGE_2_G);
  mpu.setFilterBandwidth(MPU6050_BAND_21_HZ);


}

void loop() {
  // put your main code here, to run repeatedly:
  sensors_event_t a, g, temp;
  mpu.getEvent(&a, &g, &temp);
  Ax=a.acceleration.x/9.81;
  Ay=a.acceleration.y/9.81;
  Az=a.acceleration.z/9.81;
  Serial.print("Ax:");
  Serial.print(Ax);
  Serial.print(',');
    Serial.print("Ay:");
  Serial.print(Ay);
  Serial.print(',');
    Serial.print("Az:");
  Serial.print(Az);
  Serial.print(',');
 Serial.print("UL:");
 Serial.print(1);
 Serial.print(',');
 Serial.print("LL:");
 Serial.println(-1);


  delay(50);

}

#include <Adafruit_MPU6050.h>

#include <Adafruit_Sensor.h>

#include <Wire.h>

float Ax;

float Ay;

float Az;

Adafruit_MPU6050 mpu;

void setup() {

// put your setup code here, to run once:

Serial.begin(115200);

mpu.begin();

Serial.println("MPU6050 Started!");

mpu.setAccelerometerRange(MPU6050_RANGE_2_G);

mpu.setFilterBandwidth(MPU6050_BAND_21_HZ);

}

void loop() {

// put your main code here, to run repeatedly:

sensors_event_t a, g, temp;

mpu.getEvent(&a, &g, &temp);

Ax=a.acceleration.x/9.81;

Ay=a.acceleration.y/9.81;

Az=a.acceleration.z/9.81;

Serial.print("Ax:");

Serial.print(Ax);

Serial.print(',');

Serial.print("Ay:");

Serial.print(Ay);

Serial.print(',');

Serial.print("Az:");

Serial.print(Az);

Serial.print(',');

Serial.print("UL:");

Serial.print(1);

Serial.print(',');

Serial.print("LL:");

Serial.println(-1);

delay(50);

}
