Simple MPU6050 IMU + Arduino GYRO Bot

About: My very first instructable is a contest entry. I call it passion

Using a Gyro to control my projects was a big thing on my bucket list but apart from acquiring the IMU the rest was hard as nails. The lack of effective content on extracting yaw pitch and roll values bugged me for over a month. After numerous websites, countless libraries and problems I learned to get data from the gyro and use it in a simple project that beginners can easily do and save themselves a lot of trouble.

So here's a instructable to get you started on this Accelerometer - Gyroscope sensor and by the end of it you'll be able to turn your robot exactly the amount you wish.(90 degrees, 45 degrees ,180 degrees.....anything)

Supplies:

Most of the electronis can be bought in your local electronics store or online

Here are they:

You could also use a 2 wheel chassis with a caster wheel.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Step 1 : Assemble Your Chassis

Assemble your Bot chassis lol.

Refer the fritzing image above but if you struggle , i'm just a comment below

Step 2: Installing MPU6050 Library

It's important to note that if you happen to have a library installed for your MPU6050 REMOVE IT or it will flag compilation errors.

Instead use this link to download the library and add it using Include library under Sketch.

https://github.com/jarzebski/Arduino-MPU6050


Step 3: Connections

On installing the library go ahead and wire up the
system.

The connections to the motor driver are given in the code itself.

ena = 5;

enb = 6;

in1 = 7;

in2 = 4;

in3 = 9;

in4 = 8;

here’s it anyway :)

The connections between the Arduino and the sensor are :

VCC - +5V

GND - GND

SDA - A4

SCL - A5

Note - From here on we call the robot Barney.

Step 4: Code

Copy this code below and paste it on your IDE and upload.

Couple Precautions:

Don't plug your sensor in the bread board as the wires and electronics may create noise which will affect the accuracy of your YAW PITCH ROLL values

While running the bot just set the bot on the floor and press reset so the sensor calibrates properly.

We only use the Yaw values for this project so keep that in mind while mounting your sensor.

Use double sided foam tape to stick the sensor to the front of your bot.

This instructable taught you to use a gyroscope in a simple robotics design and you can experiment with your own ideas as you now know the implementation.
