9-Axis Inertial Measurement Unit (IMU)

Our 9-axis BNO055 9-axis sensor connected to our Aurduino Nano

In this series of lessons, we will teach you step by step how to create an intelligent 9-axis IMU using the Arduino microcontroller and a BNO055 sensor. We will explain how the acceleromters, gyros and magnetometers work, and we will take you through the math you need to know. Additionally we will show you how to visualize the data coming from the sensor in stunning Vpython 3D simulations. We will explain in detail both Euler Angles and Quaternions. Below are links to all the lessons in this incredible free class.  To play along at home, you will need an Arduino Nano, and an Adafruit BNO055 Inertial Measurement Sensor.
