Arduino Prototyping Inputs #60: Digital Compass
HTML-код
- Опубликовано: 31 авг 2019
- Being able to sense your compass heading can be very useful, especially with robotic platforms. It’s best used over shorter distances, and it’s not as reliable as GPS, but it is fairly inexpensive and easy to implement.

Awesome video. Clean, precise and to the point.
I appreciate your time and help
Can I use this in a place where I have so many iron powder and magnets, by using this I want to measure the differences in magnetşc field?
Well I got the wrong breakout board lol. New one coming hope it will work. Can you point me to a good site to use this for a autonomous robot car I am make. The first part I am doing is to get it to follow a compass heading. I don’t want to copy code but would just like some pointer and a place I can refer to. Thanks
have u done with your autonomous car? if so, how was it.
I am not getting any value of x,y & z. The command mag.getEvent(&event); is not working?
Are you using the same components? Did you instal the library and use the included example? Sounds like maybe the I2C isn't wired correctly or maybe not included?
The values are not changing however I turn, what might be the problem?
Impossible to troubleshoot via comments on RUclips, but I would double check all your wiring. Next make sure you get some kind of serial connection in the serial monitor (also make sure you have the correct baud rate). If all else fails, rebuild the whole circuit based on the components data sheet, etc. Hope this helps. Again, tough to do without knowing what you made, what component you used, how you wired it up, and in a comment! Good luck! Double check everything.
Need help!. Mine is L883 chip which is actual hmc5883l but still it's not working. I'm just getting the board info as output. What could be the issue? I'm sure about the connections. Running it with Arduino nano
I'm sorry, I don't know what an L883 chip is? I looked it up and no results. You should check the datasheet for specific pinouts if it isn't what I show in the video.
My project is Self Parking Chair can I use HMC588L magnestoresistive sensor for self parking chair?
That would most likely be 1 component of a multi-component system. It will give you a fairly accurate heading (direction) but not a specific location. You will most likely need object detection and other sensors for a complete system. Take a look at what TESLA uses for their self parking car. It's very similar, and has the same goals. Keep in mind that anything that interacts with humans also need to be extremely safe and have redundant safety systems.
How can I measure current with this sensor ?
With a digital compass? It's not the correct sensor for measuring current. There are lots of ways, including using something like an Allegro Microsystems ACS712.
