I wanted to know if anyone has experience with a magnetometer or digital
compass. I assume they are the same sensor but with two names.
I am building a robot lawn mower and wanted to know if a compass would allow the robot to cross the lawn in a pattern using a north south or east west heading.
I have never used this sensor but I read they need to be calibrated and are sensitive to tilting.
I would like to hear your opinion on a part that doesn't need calibration and is accurate enough for this purpose.
