Intro: Head Mouse With MPU6050 and Arduino Micro

Hi everyone, here it is my new project, a mouse controlled with the movement of the head!
I decided to make this project once I received my accelerometer/gyroscope MPU6050 from IC Station, and I wanted to do something useful with this.
Then I found out that a "Head Mouse" already exists, made by Martin Millmore with another accelerometer/gyroscope: https://www.instructables.com/id/Head-Mouse-Game-controller-or-disability-aid/

Well here it is my version, made with an Arduino Micro and a MPU6050.

Thanks to IC Station http://www.icstation.com/ for the accelerometer/gyroscope they sent me, allowing me to create this project!

Step 1: Materials and Tools Needed

Materials needed:
- Arduino Micro;
- accelerometer/gyroscope MPU6050;
- a Compeed box (I found this comfortable as Martin Millmore said in his guide);
- an elastic band;
- micro USB cable to USB type B (like those used for Android smartphones);
- cables;
- a pcb board;
- glue, or better, Sugru.

Tools needed:
- a computer with the Arduino IDE installed;
- soldering station;
- mini drill.

Step 2: Building

1) Solder on the pcb board the pins like in the image: pin 2 of Arduino to pin SDA, pin 3 to SCL, pin 5V to PWR, pin GND to GND.
2) Make a hole with the dremel on the Compeed box so the micro USB cable can reach the Arduino Micro, and two straight holes for the elastic band.
3) glue the board to the box and add the elastic band.

Step 3: Code

Connect the board to your computer and load first the "Test" code to the Arduino to test if everything work fine. You'll probably need to change some values (everything is written in the code's comments) since I had to add a constant, beacuse values from the gyroscope are not "zero" when I'm not moving.
Use the Serial Monitor to check if you need to fix the "zero" of the gyroscope.
Once you found the right values you can load the program deleting the "Serial.print" part, that is equivalent to the standard code.
If you want the click function after a delay of time since the pointer has been in a 10x10 pixel zone load the code "with_click" to Arduino Micro.

Here there are the codes:

- standard code with only movement: https://www.dropbox.com/s/hnrhdtsoqzi8azr/Mouse_Gyro_ENG.ino?dl=0

- code to test the output: https://www.dropbox.com/s/t2f63ichd4g93n1/Mouse_Gyro_TEST_ENG.ino?dl=0

- code with movement and click after 2 seconds: https://www.dropbox.com/s/vdsg8jo1toebt4d/Mouse_Gyro_with_click_ENG.ino?dl=0

To use them you'll need the MPU6050 and I2C libraries:

MPU 6050: http://arduinomeetslinux.com/download/MPU6050.zip

I2C: http://arduinomeetslinux.com/download/I2Cdev.zip

In this site I found the libraries and the code from which I developed the programs of my project: http://arduinomeetslinux.com/content.php?p=5

Mouse_Gyro_ENG:33: error: 'Mouse' not found. Does your sketch include the line '#include <Mouse.h>'?
Mouse.move(vx, vy);

You must use an Arduino with Mouse libraries compatibility, like Micro or Leonardo.

Hello, first of all, I must say thank you for helping me doing this project. But I'd like to improve your code, with your code you just only click once, so you can't open folders, in order to be able to open folders I suggest you to write 1 click and 1 press with a delay between them, so you don't click twice but it opens the folder too.

I'm adding an image with what I mean to change.

Always easier to start something new when someone walks you through it, thanks :)
I soldered the MPU6050 directly to the Arduino to save space (4cm of cables in all) and the "at rest" values for my module were -700 and 75.
Mounted it into my DIY headlamp (left ear has a LED brightness knob, maybe I'll put mouse sensitivity over the right?

WOW! I'm really happy it was helpful!
Your project is really interesting, the robot looks really good!
I'll take a better look when I have more time, I'm interesting in the algorithm that control the track of the robot

No, you need an Arduino Micro or Leonardo, which have the "ATmega32u4" that interfaces directly with the PC and can be recognized as mouse or keyboard. See more by Googling "Arduino Leonardo" and "Arduino Micro" and check the description on the Arduino official sites.

ok.

i could implement other tasks, such as sustained click or secondary click, this with respect to programming?

I made a version which runs on every Arduino model using serial communication and python, but apparently I can't post the link here D:

The sensitivity.

As the sensor values can vary quite a lot this helps to keep the pointer calm.

If you increase it, the pointer becomes slower,

if you decrease it, the pointer becomes faster.
