Introduction

In this project, we will make an air mouse and gesture control mouse using an Arduino Leonardo and MPU6050 accelerometer and gyroscope module. The project depends on 2 key components: the MPU6050 module and Arduino Leonardo. The MPU6050 helps us to collect the data for the 3D pose of " AIR MOUSE" along the X and Y-axis. Then board on the values of the sensor can control the mouse cursor.

SPECIFICATIONS

GY-521 MPU6050 3-Axis Acceleration Gyroscope 6DOF Module

The MPU6050 contains both a 3-Axis Gyroscope and a 3-Axis accelerometer allowing measurements of both independently, but all based around the same axes, thus eliminating the problems of cross-axis errors when using separate devices.

• Accelerometer ranges: ±2, ±4, ±8, ±16g
• Gyroscope ranges: ± 250, 500, 1000, 2000 °/s
• Voltage range: 3.3V - 5V (the module include a low drop-out voltage regulator

Use: The MPU6050 is a 6 DOF (Degrees of Freedom) or a six-axis IMU sensor, which means that it gives six values as output. Three values from the accelerometer and three from the gyroscope. It is basically used as a mouse.

Arduino Leonardo

Arduino Leonardo is an old board but the only compatible board for this project. It has the required SCL and SDA pin for connection of MPU6050.

CIRCUIT CONNECTION

• Connect VCC and GND pin of Arduino Leonardo to the breadboard for making further VCC and GND connections.
• Connect VCC and GND pin of Arduino Leonardo to the breadboard for making further VCC and GND connections.
• Connect the VCC pin of the MPU6050 Accelerometer module with the positive rail on the breadboard.
• Connect the GND pin of the MPU6050 Accelerometer module with the negative rail on the breadboard.
• Connect the SCL pin of the MPU6050 Accelerometer module with the SCL pin of Arduino Leonardo
• Connect the SDA pin of the MPU6050 Accelerometer module with the SDA pin of Arduino Leonardo
• Attach both the push buttons with breadboard
• Now connect each pin of push-button with the negative rail on the breadboard as shown in the diagram.
• Connect push button 1 (for Left click) with the digital pin 7 of Arduino Leonardo
• Connect push button 2 (for right-click)with the digital pin 6 of Arduino Leonardo

NOTE- To click the mouse you need to stop moving the mouse and lock it to a point for 2 sec so you could integrate a button for this purpose. you can add a button for this function we have not added in the circuit but it is mentioned in the code as it connected to the digital pin 1 of the Arduino Leonardo.

OUTPUT

Welcome to the Arduino based project in which you can control the gesture by MPU6050 module. The first push-button is for left click and the second push button is for right-click.
