pendulum + nano 33 ble sense - andrea.colonna - 02-27-2022

Hello,
 I adapted the phyphox pendulum experiment on the nano 33 ble sense microcontroller. 
I am attaching the scretch .ino and the .phyphox file.
I would like to carry other experiments on the microcontroller but I have found difficulties regarding linear acceleration. Is it possible to obtain the linear acceleration values (no g) from the arduino board?
Thanks!
Andrea

Hi Andrea,

a so-called sensor fusion of the IMU sensors is required for a “linear acceleration”. AFAIK, the gyroscope and magnetometer need to be calibrated for meaningful data. These two threads might serve as a starting point: https://forum.arduino.cc/t/nano-33-ble-problem-with-imu-and-madgwick-libary/636245 and https://forum.arduino.cc/t/nano-ble-33-sense-lsm9ds1-sensor-fusion/696909
