Story

It's just an experiment :

I was thinking can M5stack work as a mouse for my PC
then I did some programming and a little bit of research.
And Yeah It's possible.

How I Made This:

As I have the core kit of M5Stack Core there is no imu in it. so that's why I added an MPU6050 in it. to get all data I need.
I use some female headers to connect it

and connected it to M5Stack.

VCC ---- 3.3v

GND ---- GND

SCL ---- SCL

SDA ---- SDA

How it works:

firstly we need to understand these terms.

so we move in the X and Y plane on the PC screen.
so I am using pitch and roll.
so if roll >= 40 then it will write H in the Serial.
then by using python serial lib.
we are able to read serial values.
then if it finds H in then it will move the mouse in +5 in the x-axis.
so if roll >= -40 then it will write B in the Serial.
then by using python serial lib.
we are able to read serial values.
then if it finds B in then it will move the mouse in -5 in the x-axis.
so if pitch >= 40 then it will write L in the Serial.
then by using python serial lib.
we are able to read serial values.
then if it finds L in then it will move the mouse in +5 in the y-axis.
so if pitch >= -40 then it will write P in the Serial.
then by using python serial lib.
we are able to read serial values.
then if it finds P in then it will move the mouse in -5 in the y-axis.
so if the B button (middle button) is pressed then it will write C in the Serial.
then by using python serial lib.
we are able to read serial values.
then if it finds C in then it will simulate the left click of the mouse.

MPU6050:

so I'm using the sketch that comes with the M5Stack library.

I'm modifying the sketch as per my need.

Lib needs to install:

install serial from here.
install pyautogui from here.

How to use:

firstly upload the Arduino code that I gave on M5Stack.
then paste code on the python interpreter then run the program.
WARNING: don't close Arduino ide while using M5Stack mouse.
