MPU sensor has many functions over the single chip. This module is very accurate while converting analog values to digital because it has a 16bit analog to digital converter hardware for each channel. This module is capable to capture x, y and z channel at the same time.

It has an I2C interface to communicate with the host controller. This MPU module is a compact chip having both accelerometer and gyro. This is a very useful device for many applications like drones, robots, motion sensors.

It is also called Gyroscope or Triple axis accelerometer. MPU is an 8 pin 6 axis gyro and accelerometer in a single chip. This module works on I2C serial communication by default but it can be configured for SPI interface by configuring it register.

Almost all the pins are multifunctioning but here we are proceeding only with I2C mode pins. This module gives us row values and normalized values in output but row values are not stable so here we have showing normalized values over LCD. In this project, we have first shown a temperature value over LCD and after 10 seconds we show gyro values and after 10 seconds we have accelerometer readings as shown in the images below:.

And here we have used a laptop USB power supply. A 10k pot is used for controlling the brightness of the LCD. In connection with MPU, we have done 5 connections in which we have connected the 3. Data pin are directly connected to digital pin number 10, 11, 12 and Programming part is also easy for this project.

Here we have used this MPU library to interface it with Arduino. After it, we can find example codes in the example. The user may test that code by directly uploading them to Arduino and can see values over serial monitor. Or the user may use our code given at the end of the article to show values over LCD and serial monitor as well. In setup function, we initialize both devices and write welcome message over LCD. MPU gyro and accelerometer both are used to detect the position and orientation of any device.

Interface Accelerometer With NodeMCU

Gyro uses earth gravity to determine the x,y and z-axis positions and accelerometer detects based on the rate of the change of movement. We already used the accelerometer with Arduino in many of our projects like:.

Did you use the same library mentioned in the article. I used the same library mentioned in the artcle. I have done everything as described but my lcd lights up but does not display the text. Adjust the pot and try. I copied your code its working upto LCD coding after that its not working why is this happening. In loop Function, we have called three functions in every 10seconds for displaying temperature, gyro, and accelerometer reading on LCD.

These three functions are tempShow, gyroShow and accelShowyou can check those functions in the complete Arduino code given at the end of this article:. Recommended Posts. Didn't Make it to embedded world ?

No problem! Fundamentals of IoT Security.Before going in to the project, you need to understand a few basics of the MPU Sensor. IMU Sensors are used in self-balancing robots, aircrafts, mobile phones, tablets, spacecraft, satellites, drones, UAVs unmanned aerial vehicles etc.

In case of MPU, it is a six-axis motion tracking device that combines a 3-axis Accelerometer and a 3-axis Gyroscope on a single chip. We will see more details about MPU in the next section.

The main features of the MPU device are mentioned below. Digital Motion Processor or the DMP is an embedded processor that can reduce the computational load from the host processor, like an Arduino, by acquiring and processing data from Accelerometer, Gyroscope and an external Magnetometer.

Coming to the MPU, we have used a normal breakout board that provided eight pins. The above image shows the schematic representation of the MPU Breakout board. Pin 2. Before uploading the actual program, we will first see a simple program to read the raw values from the Accelerometer, Gyroscope and the Temperature Sensor. If you open the serial terminal, you will get the raw values from the Accelerometer and Gyroscope and calibrated Temperature from the Temperature Sensor.

The data looks some thing like this. As you can see, reading the raw values from the MPU sensor is easy but this data and we need to perform additional calculation on this data to get the Yaw, Pitch and Roll. The use of this DMP is that it can be programmed with a firmware for performing complex calculations on the data from the sensors. Jeff Rowberg and others has done an excellent job in reverse engineering the DMP related information from the I2C signal analysis.

Before uploading the code, we need to download two libraries for Arduino. The download links and the official GitHub links are given below. Download the MPU Library and extract the content by unzipping the downloaded file. Copy this folder and paste it in the libraries folder of Arduino. Do the same thing for I2Cdev library. Upload this code to Arduino assuming that you have already made the connections as per the circuit diagram and once the code is uploaded, open the serial terminal.

Set the baud rate in the serial terminal to and you will get the following text. So, type any character like 1 or a in the serial monitor and send it.Did you use this instructable in your classroom?

Processing is mainly used for visualizing data. This library is necessary for our the MPU processing example. You can subscribe to the my YouTube channel for more tutorials and projects. Subscribe for support. Thank you. Thanks for this great and easy tutorial! I would also like to learn about how to read values from MPU via Processing console when simulation runs, because now i can't read any values.

Using Arduino's serial monitor i can read values, but they aren't stable, altough i don't moving the MPU module at all!

Question 2 years ago on Step 5. Hey there, I'm wondering how do i change the code to just read 1 axis values so i can interpret them within a acceleration vs time graph? FYI the values would be exported to an excel spread sheet via usb we have that part done. Im just needing help with getting the values needed. Any help most appreciated - Michael Lees.

I've been playing with it, but haven't had much luck getting to stay centered and simply tilting as I tilt the sensor. According to this, it seems you have project a reference frame in order to avoid drift, but there's no example!

The output that I am getting at the Serial Port Monitor is. First of all, don't declare any global variable to store your acceleration and gyro value, it can cause a problem in case you have nested loops.

It's better to declare them inside the loop only or use the static keyword. I had the same problem I resolved it in this way. Your addresses are right but still, you can refer to the datasheet.

It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration. In general, ADXL is 3v3 compatible device, it's powered by a 3.

It has three outputs for each axis, i. These are analog outputs and thus require an ADC in a micro-controller. NodeMCU solves this problem. We will be using the analog pin of NodeMCU.

If you have a small project and would like your own dedicated place to post and have others chat about it then this is your spot. It all worked out quite well, but I want to make the whole setup a bit smaller because I want to place one sensor on each wrist, and that would be an Arduino Uno on each wrist.
