Raspberry Pi Pico & MPU9250 with MicroPython. Do you want to know how to use an MPU9250 Accelerometer, Gyroscope and digital Magnetometer to position your robots? Then this is the video for you. In this video we will look at: - how the MPU9250 works (its actually two chips combined into one package), - how to calibrate and dampen the readings to make them usable - how to convert the raw x, y, z readings into degrees and radians For more information, tutorials, parts and more visit: https://www.smarsfan.com/​ Enjoy this video?
