"Hello everyone!
I don’t speak English, sorry if there are any mistakes.
I was previously working with App Inventor, where I used the orientation sensor, and it worked well. I wanted to remake this application with Thunkable, but the magnetometer associated with the heading block is not working correctly (+90 degrees, it’s in the wrong quadrant). The calculations seem to be done with ‘atan’ instead of ‘atan2’, and I don’t understand why… Can anyone help me?"
Thank you in advance 🙂
