Review on 🧭 Songhe GY-271 QMC5883L 3-5V IIC Triple Axis Compass Magnetic Sensor Module Electronic Compass Module for Arduino - Pack of 3 by James Pfettscher

All example sketches provided seem to work except ONE that needed to be run: Calibration procedure. When this is running it tells me to move the board in all directions until the sketch tells me to stop and gives me a set of calibration values to add to my sketches. I ran the calibration repeatedly, and sometimes it would count up to 30,000 and then stop doing anything. On other occasions he would count to a few hundred and stop. Very unpredictable. The last time I ran it, I moved the sensor as directed for over 5 minutes. The calibration sketch never came back with any calibration values. Too bad. I really wanted to add this feature to the project I'm working on now. They are going back.
