This raw data shows the main orientation data, consisting of 'roll', 'pitch' and 'heading' (or 'yaw) in degrees, followed by the current altitude and temperature
The AHRS sketchs reads raw data from the board's accelerometer/magnetometer and converts the raw data into easy to understand **Euler angles.**
In this case, we can see that the **roll is about 18°**, the **pitch is about 78°** and the **heading or yaw is about 32°**, and the sketch will keep updating itself with the latest values at whatever speed we've set in the sketch.
