How to easily use HMC5883L Compass Sensor

[@gvnsatwik4693]

Bro i tried exactly same but it isnt displaying any information other than sensor name and other till resolution .but i am not getting any values of co ordinate can you help me ?

[@miliohm]

Maybe you got the qmc version, try this: miliohm.com/how-to-use-or-fix-hmc5883l-compass-sensor-that-doesnt-work-on-arduino/

@@miliohm yeah ! Thats working thanks for the help man ...love you 😘

@@miliohm Mine is original one which is Hmc but still I'm not getting any x y z values. It prints the board info alone as he said. What should I do now?

[@miliohm]

@@sanjaybalasubramanian9468 how can you tell it's original? Did you try use qmc library?

[@martinmartin38077]

Thanks for the guide. Very useful. I am an Arduino 'virgin', and this was my first attempt to get something working for a compass on my telescope. I had an issue with uploading the library. I kept getting the error "exit status 1". I had to uninstall my CH340 COM driver, and install one independently. Once I got passed that issue, all worked great. Thanks for making my first steps easy. I think the chip needs calibrating. That would be a useful addition to this guide

[@sre2007]

My hmc5883L is 3V OR 5V so I suggest the wiring diagram be changed to reflect this option. I think using the 3V option is better in a "magnetic" setting, since 5V would create more EMF in it's own operation, right?

[@fabse-hack]

you make an calibration of the sensor?

[@keithschaub7863]

how do change to different Apins? I'm already using A4 and A5 for the ultra sound. I'd like to use A1 and A2 for the mag sensor - do you know if this is possible?

[@miliohm]

On arduino Uno, i2c only available on A4 and A5 (SDA & SCL). So you don't have another choice.

[@miliohm]

If the ultrasound is not i2c, you should move the ultrasound.

I tried same but with esp32 board and the heading is being displayed very wrong. It is stuck at 237.61. no matter how much I rotate the magnetometer horizontally, it remains the same.. I tried removing power of magnetometer. Amazingly, the reading was being updated the same even when the magnetometer was removed. I am stuck here and it doesn't seem to work. What do I do?

[@tunahanatmaca7059]

Hey man! Did you solve this problem? I am also having the same issue.

[@jumpingeal1928]

@@tunahanatmaca7059 Found the problem with this issue, it's because the library that this video is using is assuming the I2C device has the address 0x0C when it's 0x0D. To get it working I used the library "DFRobot_QMC5883" instead (search it up on arduino library explorer). then download their example code and on line 13 chance the VCM5883L_ADDRESS to 12 (which is the address 0x0D). lmk if this works, I might make a youtube video helping others fix it

[@santiagobermudez7290]

@@tunahanatmaca7059 i have the same problem i tried with esp32 and arduino, it gives me the same value. i think the sensor is damaged.

[@estudiantecomputerscience]

Thank you so much!

[@findinmydearestbro1569]

Hi! i it just me or whenever I try to connect my arduino it turns off

[@sinnesia2958]

I think adafruit library much simpler than other libraries.

[@tudor5398]

Is it possible that it odesn't work with an Arduino MEGA?

[@miliohm]

Should works the same way. It just use different pins

[@bleednlov]

Where is the code for the HMC5883L? It is not on your "full code and tutorial" link, there is only a .png of it.

[@miliohm]

You should read carefully

[@Amperekaefer]

*Danke* für das interessante Video. Ist die störende Hintergrund-Musik wirklich nötig??

[@miliohm]

danke für deinen Input, werde die Lautstärke verringern (Google Translate)

[@Amperekaefer]

Oder ganz weglassen, Du hast so eine schöne Stimme.

[@juremyclorkson3518]

thank you Borat

[@findinmydearestbro1569]

why does my arduino turn off if I connect gnd to gnd

[@miliohm]

Probably it's not gnd but vcc

[@findinmydearestbro1569]

same thing happens to vcc to vcc @@miliohm

Thank you fron showmik vai and me

[@yusufmaulana960]

bang, coba bkin lagi dong, tapi kali ini ditest ama interferensi magnet permanen. [kompasnya error ngak kalau deket ama magnet, dan kalau ada eroor, berapa jarak minimum agar error itu hilang?]

[@mrbhakcho]

bro code is not available on ur site

[@miliohm]

You just need to download the library and use the example there

[@dharsonraju5390]

I am getting the same values repeatedly

[@jayvratsinhjadeja8299]

I had the same issue, then I just connected it to 3.3v supply from Arduino and it started working.

In the real world, these devices are neither accurate or stable enough.

[@ptoktedia9011]

how? and what sensor then is reliable?
