Read the Arduino MPU6050 documentation correctly (I’m sure I have) and include the necessary library files. The documentation for this doesn’t explain you have to add the I2CDevice and BusIO Libraries, which for a beginner turns out a tad frustrating.

CHANGED the ‘Basic readings’ example file to:
#include <Arduino.h>
#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>
#include <Wire.h>
#include <Adafruit_I2CDevice.h>

- Which now works BUT…
mpu.setAccelerometerRange(MPU6050_RANGE_8_G); Does NOT set to 8G it’s 16G?
mpu.setGyroRange(MPU6050_RANGE_500_DEG); Does NOT set to 500DEG it’s 2000DEG?
mpu.setFilterBandwidth(MPU6050_BAND_21_HZ); Does NOT set anything?
Any help very much appreciated.
