In this new tutorial series we will take you step by step through creating a 9-axis IMU capable of monitoring an object’s orientation in 3 dimensional space. In this first lesson we introduce you to IMU and 9-axis sensor basics, and outline the gear we will be using in these lessons. To play along at home, you will need an Arduino Nano, and an Adafruit BNO055 Inertial Measurement Sensor.
