But in this project other type of Arduino dev. kit such as UNO, Mega, Nano won't work. Because, for I2C communication from the board to the computer we'll need a dev. kit which supports native serial USB. So in this project, you'll need these components:

Arduino Leonardo/ Micro

MPU 6050 (3-Axis Accelerometer)

10K ohm resistor

Break board

Push button switch

Wires

Hope, you already connected the circuit as shown in the diagram & uploaded the code. If this is working well then it's good. But flaws can appear anytime. Let's focus on them.

#Problem_1: My buttons are auto working. Solution: Then, check the connection again, cause only loose connection causes these kinds of problems.

#Problem_2: My cursor is not stable it's moving automatically or fluctuating a lot. Solution: Change the calibrating values of X & Y plane as shown in the video according to your sensor. Cause different sensors have different calibration values.

#Problem_3: My buttons are reversely working. Solution: Check the type whether your buttons are Pull up or Pulldown. If found so then simply reverse the connection.

Still if got any further problems or question regarding this project lemme know in the #COMMENT section. I'll get back to you ASAP.

Code

Arduino Mouse project code using MPU6050

#include <Wire.h>
#include <I2Cdev.h>
#include <MPU6050.h>
#include <Mouse.h>

MPU6050 mpu;
int16_t ax, ay, az, gx, gy, gz;
int vx, vy;

const int button1 = 4;
const int button2 = 5;
int responseDelay = 10;
void setup() {
  pinMode(button1, INPUT);
  pinMode(button2, INPUT);
  Serial.begin(9600);
  Wire.begin();
  Mouse.begin();
  mpu.initialize();
  if (!mpu.testConnection()) {
    while (1);
  }
}

void loop() {
  mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

  vx = (gx - 400) / 200; // "-400" because the x axis of gyroscope give values about -350 while it's not moving. Change this value if you get something different using the TEST code, chacking if there are values far from zero.
  vy = -(gz - 200) / 200; // same here about "-200"
  int buttonState1 = digitalRead(button1);
  int buttonState2 = digitalRead(button2);

  if (buttonState1 == HIGH) {
    Mouse.press(MOUSE_LEFT);
    delay(100);
    Mouse.release(MOUSE_LEFT);
    delay(200);
  }
  else if (buttonState2 == HIGH) {
    Mouse.press(MOUSE_RIGHT);
    delay(100);
    Mouse.release(MOUSE_RIGHT);
    delay(200);
  }
  Mouse.move(vx, vy);

  delay(20);
}
