About The Project

• The Aim of the Project is to make a Mouse using the data fusion DMP(Digital Motion Processing) of MPU_6050 and ESP32 with Bluetooth support to actually make it easier for the user to move pointer in any position they want.

• The Support for Right and Left click is also established using Capacitive touch pins of ESP32.

  

Tech Stack

The Technologies used for this project are

• FreeRTOS
• ESP-IDF

Getting Started

Prerequisites

Install ESP-IDF : https://github.com/espressif/esp-idf

Installation

Clone the project

https://github.com/gautam-dev-maker/Air-Mouse.git

cd Air-Mouse

Usage

Build

idf.py build

Flash

idf.py -p (PORT) flash monitor

Configuration

idf.py menuconfig

• Example Connection Configuration

  • Bluetooth Name - Set Bluetooth Name

• `MPU6050 Configuration

  • SDA Pin No. - Set SDA Pin No.
  • CLK Pin No. - Set CLK Pin No.

• The default Pin configuration used to connect MPU_6050 with ESP32 in this project is shown

Results and Demo

The use of Right and Left Capacitive touch pins has been demonstrated in the following videos

Right/left buttons

Troubleshooting

While Configuring for the first time if Bluetooth is not working then ,go to terminal

idf.py menuconfig

Then go to components/bluetooth and enable bluetooth Press ctrl+s to save the configuration then

idf.py build
