I am a software developer and need something that doesn't assume that I know how to do it already. Searching Google has only found diagrams that I can't read or textual instructions where the terms don't match up to the names on the pins on the Uno R3.

I don't know what they are talking about ch1 Tx and Logic Level Converter. I presume you have seen this page. If not it's probably a good place to start. All you should need to do to talk to that GY chip is to hook up the I2C pins. Luckily, this problem is easily solved with a couple of transistors as described in excruciating detail on this page and various answers to similar questions on this site.

Question feed.As usual before making any intermediate or advanced level project, first I am going to explain the basics that every beginner should know. In this tutorial, I will try to keep things simple so that you can easily understand the whole mechanism. The components and tools used in this project can be purchased from Amazon, the components Purchase links are given below:.

Please Note: these are affiliate links. I may make a commission if you buy the components through these links. I would appreciate your support in this way! This module needs 3 to 5 volts. This Module can be used in a hand gesture controlled Robot, wheelchair, earthquake detection system, Self-balancing Robot, the self-balancing platform for a camera, Segway, etc.

As you can see clearly this module has a total of 8 Pins which are clearly labeled. This schematic is designed in Cadsoft eagle 9. The circuit diagram is very simple, as you can see VCC is connected with 3.

The MPU Eagle library can be downloaded which is given below.

Connect the Orange wire which is the VCC wire with 3. Before you start the programming, first of all, make sure you download the following libraries. If your Arduino IDE is open close it and open it again. Each time you add a new library you should reopen the Arduino IDE in order to load the library files. While the Arduino is connected with the Laptop, first Upload the program and then open the Serial Monitor and make sure you select as the baud rate.

In the demonstration video given below, you will see that the ax, ay, and az value changes as I rotate the MPU Module. For the easy calibration, I am going to fix this sensor on a Vero Board.

You can watch the soldering in the video given below. The pins of the MPU are soldered with the female headers.Pages: [1]. Hello, I've been toying with my GY breakout the last few days, and I have been able to get a cursory understanding of how it works. What I would like to do with it is to wake up an AtmegaP-PU using an interrupt if persistent movement is detected that lasts longer than one second, give or take, and that movement must have a certain magnitude, i.

I want to filter out accidental movements and only let the Atmega alert when there is really something going on. If somebody actually manages to start the car and drive off with it, the device will wake up via a pin change interrupt that's connected to the car's speed signal.

But if, say, my car gets towed, I want the device to wake up as well and start sending GPS data. To make sure the Atmega doesn't wake up everytime the car moves ever so slightly in a gust of wind or somebody just leans against it the wrong way, I would like to filter out the kind of movement that that will create.

It looks to me like a relatively simple application, but I can't really figure out where to start and how to do that using a few simple lines of code.

I have looked at the example sketches of the MPU library, but that hasn't really helped so far in trying to write code for my purposes. Could somebody point me in the right direction as to how I can achieve what I would like to do? Re: using GY interrupt to wake up Arduino. Unfortunately the documentation for the DMP is not freely available at least I wasn't able to find it.

Here's a different approach: The GY seems to draw somewhere around 6. So there'd be no harm in keeping both it and the AtmegaP-PU in continuous operation without putting the Atmega to sleep.Are you looking to make your own quadcopter drone or RC plane with Arduino but don't know how to get the gyro working?

Perhaps you already bought some 6 axis MPU modules on the GY breakout boards only to find out they weren't as simple to use as you thought? Try this out! This is intended as a learning tool to get you familiar with gyro modules, breakout boards and installing the necessary libraries to your Arduino IDE to allow you to make the best use of your MEMS gyro and save time instead of writing complex code from scratch.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The breakout board comes with pins but requires soldering. If we were to write the code from scratch, it would take ages and there would be a lot of reverse engineering required to make good use of the module's proprietary Digital Motion Processing DMP engine because Invensense intentionally released minimal data on its MPU They are available as a zip file from here:.

Once unzipped, find the Arduino folder within it and copy the two folders "I2Cdev" and "MPU" over to your Arduino "libraries" folder in the following directory:. Open it, plug your arduino in, select the appropriate COM Port and upload the sketch. In the Serial Window, select a baud rate of You should be prompted that the MPU connection was successful.

You can test the data collection by typing anything in the text bar and pressing enter, the data should start showing up. Now we want to set the code to run the teapot demo to show the 3D simulation.

Select "save as" and choose where you want to save the modified code. Upload again but don't open the serial window this time. However the Arduino IDE will only be acquiring the data, to display the 3D simulation we'll need additional software: Processing. Download Processing from here, then unzip to wherever you like:.

We'll need one final library to get things running: ToxicLib. This library will be going into Processing's libraries folder instead of Arduino's. The latest version of the ToxicLibs library is here:. Click the play button and the system should calibrate for about seconds, leave the gyro stationary during that period.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Read the values of the accelerometer and the gyroscope. The accelerometer measures the acceleration along one direction, while the gyroscope measures the angular acceleration on one axis. The values read by the analogic pins will be sent to the serial port. Open the S erial Monitor, move the sensor and try to see how the values change. Please log in or sign up to comment. This code enables you to make an accelerometer and gyroscope give the best results.
