Adventures in Science: Using a Magnetometer as a Compass

A magnetometer is any instrument that can be used to measure magnetic fields. Developments in semiconductor and microelectromechanical systems (MEMS) in the past few decades have afforded us digital magnetometers that can be used to take precise measurements of these fields. Because the Earth acts as a giant magnet, we can use magnetometers to find the direction of the Magnetic North Pole. This could be extremely useful on robots that need to determine a heading to, say, autonomously navigate a course.

Like the MicroView, have only 1 (for now).
Been using various forms of the MEMS for a while and have noticed just like ole magnetic compass, they can give false readings just by passing something big & metal.
But they are fun to work with.

Love the bloopers, my fellow nim-na-hue!

Can you do this for the LSM9DS1 please?

I have no idea what an Arduino is. Be easy on me! but I am trying to link a nozzle mounted “compass” to an onboard boat GPS so that I can get directionality for herbicide spray patterns. It sounds like this is something you could achieve with a small setup like you showed. I’m sure it’s much more technical than I imagine

great video

[@memoresendiz4727]

thank you very much

[@jdcravens3609]

Cool I guess

Great tutorial! But the bloopers sucks!
