How to Use Accelerometer, Gyroscope and Magnetometer with Arduino: A Step-by-Step Tutorial

If you are looking for a step-by-step tutorial on how to use accelerometer, gyroscope and magnetometer with Arduino, then look no further. In this article, we will guide you through the process of setting up your Arduino board to communicate with these sensors.

Before we dive into the technicalities of working with these sensors, let’s first understand what they are and how they function.


An accelerometer is a device that measures acceleration forces in any given direction. It can detect movement in all directions and is commonly used in smartphones to measure tilt and orientation. In Arduino projects, accelerometers are often used in vehicles or other machines where there is a need to monitor acceleration or vibration.


A gyroscope is a device that measures angular velocity or rotation around an axis. It functions by using gyroscopic principles which involve the rotation of an object about its axis. Gyroscopes are commonly found in aircrafts and satellites for navigational purposes. In Arduino projects, they can be used for controlling robots or measuring change in orientation of a system.


A magnetometer is a device that measures magnetic fields. This sensor detects changes in magnetic field strength and direction when it moves from one location to another. In Arduino projects, magnetometers are often used as compasses for navigation or to detect magnetic interference.

Now that we know what each sensor does let’s get started on how to set them up with your Arduino board:

Step 1: Gather hardware requirements

You will need an Arduino board and three sensors – ADXL335 accelerometer, L3G4200D gyroscope and HMC5883L magnetometer – along with hookup wires and breadboard.

Step 2: Connect power supply

Connect the red wire (VCC) from each sensor to the +5V pin on the Arduino board, while connecting black wire (GND) from each sensor to GND pin on the board.

Step 3: Connect accelerometer

Connect the X, Y and Z pins from the accelerometer to analog inputs on the Arduino board (A0, A1 and A2 respectively)

Step 4: Connect gyroscope

Connect SDA and SCL pins from the gyroscope to digital pins on the Arduino board (A4 and A5 respectively).

Step 5: Connect magnetometer

Connect SDA and SCL pins from magnetometer to digital pins on Arduino board (A4 and A5 respectively).

Step 6: Upload code

Now that everything is wired up correctly, you need to upload your code onto the Arduino. First, download libraries for each sensor and install them in your computer by connecting them with your IDE software.

Once this is done, copy-paste code scripts available online or write fresh ones based on what you want your project to do. After successfully uploading it onto your device you can run it/flash it through a serial monitor to check if there are any errors.

In conclusion, working with accelerometers, gyroscopes, magnetometers in

What is an Accelerometer?

An accelerometer is a sensor that measures acceleration forces on an object in three-dimensional space. These forces can include gravitational forces or forces caused by movement. Accelerometers essentially measure change in motion – whether it’s speeding up, slowing down or changing direction.

One common use for accelerometers is in fitness tracking devices like smartwatches; they’re used to determine step counts and activity levels. Other applications include monitoring vibrations in machines to avoid malfunctions or accidents.

How does an Accelerometer Work?

Accelerometers typically consist of two main components- mass-spring system and a sensing element . The sensing element measures changes in capacitance or resistance based upon the position of the mass-spring system which creates electricity.

When the device experiences force or movement along any axis (x,y,z), it affects the position of the mass-spring system which changes the capacitance/resistance value able to be detected using ADC pins interfaced with arduino board through breakout boards.

What’s a Gyroscope?

A gyroscope measures angular velocity (rotational speed) around different axes. Similar to accelerometers , this information is used for motion-sensitive applications such as gaming controls or robotic control systems.

Gyroscopes use MEMS technology; this means that tiny mechanical structures on chips form the gyroscope. The MEMS device detects changes in capacitance/resistance or magnetic fields based on motion in relation to the sensor, making it responsive to any detectible rotation.

How does a Gyroscope Work?

Gyroscopes essentially use applications of conservation of angular momentum to provide information about rotational forces. To detect rotational components set around various axes (x,y,z) gyro sampling frequency should be adjusted.

When a device that houses the MEMS gyroscope is subjected to any rotation its direction and force creates electrically distinguishable changes which works similar as stated above requiring an ADC pin connection for processing with arduino board.

What’s a Magnetometer?

A magnetometer measures magnetic field strength and orientation of Earth’s magnetic field or other magnetic sources. These sensors are often used for detecting north/south positioning in navigation systems and compasses, but also have countless other uses such as metal detection or monitoring geomagnetic patterns for improved weather reports.
