Use the HMC5883L 3-axis sensor with an Arduino - Tutorial

[@toothpik00]

Not "silly" at all, I can see this working for a joystick. Great video.

[@BrainybitsCanada]

+PIK Thanks for the comment, watching and the joystick idea!

[@jamescullins2709]

What is the difference in the qmc5883L and the hmc5883L? thank you.

[@cyberdeckcipher]

hey @Brainy-Bits, can you use this magnetometer sensor to sense the angle of an magnet or it goes crazy?

[@jaysongalvez4340]

What happens when you go over the limit of the x, y, or z axis? Does it reset to 0?

[@humaidalqubaisi9194]

Is it HMC5883L as in the description or as you wrote in the Code : HMC5803L ?

[@NgoniAlwin]

i would like to callibrate my HMC5883l 3 axis sensor so that it doesnt lose the heading if it is tilted bit

[@aaronchan1498]

Hi, I am looking a magnetometer that can work with a baud rate of 115200 for interfacing with ESP32. Which would be most suitable for vehicular detection operation?

[@hydayatsharabati5192]

Hello thank you for the video. I have a question can you show how to measure just the magnetic field with this sensor? Like can the sensor be attached to a cable of a device and measure when current is on and when off ?

[@walterblanc9708]

So 5v and 3.3v I2C systems work together ok then? No need for level changers?

[@sanjaybalasubramanian9468]

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

[@jefersonnl]

Can I use this (HMC5883L) to control Yaw stabilization on a quadricopter, helicopter or model airplane without the need of a separated module, like the MPU-6050? Or is it best to use the HMC5883L only to replace the biased, ever-drifting and shitty non-accelerometer assisted Z-Axis output that comes from the MPU-6050?? They say the accelerometer in the MPU-6050 is excellent(I certainly can testify for that in static testing) and can correct very well the drifts on its gyros (X and Z axis). However, when we take into account a vehicle that accelerates too much or even turno into near horizontal flights, the manufacturer of MPU-6050 is quite clear in saying that due to lateral G-Forces this, in a certain given time, can take away from the unity the source/point of reference, that its accelerometers use to un-bias the gyros, earth's gravity.

I want to create a module that force everyone to use hand rail while in stairs,so i want to trigger the metal sensor( attached to this module) while climbing the stairs , i am using combined accelerometer & gyroscope sensor , but the accelerometer is getting triggered even when i am walking , is it possible to sense a direction at around 45° from vertical using this module so that my project get successful?

[@cxgraham]

Hi, I'm new to this. Enjoying the KZbin videos. I'm thinking of building this, just wondered how to fit a buzzer and add commands so that it works when the unit is angled over and the red LEDs come on. Can you advise please? Many thanks.

[@iceman1st1]

Hi, how could I use this on a vehicle to activate the brake light's when it senses the vehicle slowing down

[@youssefdirani]

Thanks, do you know what is the unit of the read values (for s, y or z)? E.g. is it in microTesla?

[@userone7651]

a link to github with the code would be awesome.

[@Trambulin15]

Great project! I have a gy-87 sensor, which has the same hmc5883l magnetometer, and i used your code to read datas, but i got only -1 -1 -1 values. Do you have any idea why do i get only these values?

[@BrainybitsCanada]

+Trambulin15 Don't have the GY-87 version on hand so can't say if it requires different programming than the one I'm using, but that might be it! Make sure your connections are good and maybe use different connection cables to make sure it's not just a bad connection. Thanks for watching!

[@runaway2074]

+Brainy-Bits hmc5883l have name is "GY-271" but is not GY-87 and there are another one is GY-521

[@apocalypticentity7012]

Hi Mate, I know this thread is really old now, but I am leaving this here for anyone else who comes across this video. I had the same issue and I found out that the chip on my breakout board was actually a QMC5883L and NOT the HMC5883L. Hope this helps someone else out in future. Edit: "For further clarity, The I2C address is different. This might explain why you had this problem. Seems the address is 0x0D."

[@vibhvesh]

THANK YOU , i just wanted to know more about it, well explained.

[@nickdoneff]

Hi, thanks for the clear video! Does this device read rotation on the z axis? for example to serve move like a compass and send an output that could control a stepper motor proportionately?

[@navadeep025]

Please make a video on how to do it for random values of magnetic field. How can I make it work in any place by auto initialisation of magnetic fields.

[@DJcoasttt]

Hi, here's a noob question for you: If you reboot the Arduino, will the sensor take the first value as the 0 position, or is it always constant like a compass?

[@aaronchan1498]

Hi, is it possible to change the baud rate of hmc5983 to 115200 , and make it complement with esp32. I tried and got some reading errors.

[@wfung8041]

Sir, Would you mind help and teach me the guide line ? I want to turn on led light when hmc5883l ARDUINO detect motion , e.g. when the bicycle start to move, hmc5883l + ARDUINO automatic turn LED headlamp.....

[@JohnJoe131]

The serial monitor doesn't show any values, it's just blank. Why does the program not get any values from the sensor?

[@bjnacn6711]

Nice. I have this question : What values do you get if you rotate the sensor over 90 degrees around one axis? Is it still measuring something or does it get to the maximum available? if it does, do you think there's a way to map it for 180 or 360 mouvement? Thank you!

[@SKElectronics]

How accurate is this module?

[@nibras26baqir]

Would you please tell me how to contact you to talk about this ?

[@ofekyabo7403]

the program stucks after Wire.endTransmission(); and i dont know why is it i have tried to Serial.println("7"); and it writes no thing i hope you understand my problem and maybey can help me

[@akaleselassie]

HELLO HAVE YOU TRIED TO GET IT TO WORK WITH ESP8266 ESP-01 WITHOUT THE UNO?

[@jhonsalazar4801]

can you pls send me the code i just need it for our arduino

[@JerryEricsson]

I can see a great use for this our old Class A motor home has a joystick type hydrolic leveler system. The lights have long stopped working properly, so I have to dig out an old level and have the wife tell me when I am level so the rig works right, ie. the fridge needs to be near level to cool, and walking can be difficult if you are off level. Now don't get me wrong, my wife is a wonderful woman, but she cannot read a level at all for some dang reason, so each setup quickly turns into a shouting match. This could well solve our problems and poor oil on the troubled waters at RV parks across this great land.

[@_MisterG]

Thank you for sharing AND for making it easier to read the code. Quick question: I noticed you rotated the module through 90° for the readings. Is this the maximum it will measure, or could it do a full 360°? That would make it useful for a cool wearable device that I have not thought of yet!

[@BrainybitsCanada]

MisterG The X and Y axis will do 180degrees, the Z axis should be able to do 360degrees since it can be used to detect magnetic north. I will do another tutorial video showing how to use the HMC5883L as a compass soon. Thanks for your comment and watching!

[@bishantadhikari3440]

init_HMC5803L() where is it even defined?

[@furkanayas3339]

Is it measure YAW

[@username-zg8og]

Do you have any code to convert magnetometer data to PC screen coordinates? Plz anyone who have the link, reply me

[@zelra891]

this is great in some project like quadcopter. btw, you should say "i square c".

[@BrainybitsCanada]

Zelra 仙賢戀軒 Thanks for the comment, and for pointing out the i2c, didn't even notice it till now :)

[@SpeccyMan]

Actually since the protocol is actually called IIC for inter-integrated circuit you would logically call it I two C.

[@joshsat9106]

I just learned that you could use this in orbit to about 1/4 the distance of the moon.

[@1979zeesh]

+Brainy-Bits i need your help. i have sen your code and it is very professionally written. can you help me do the same but instead control speeds of 2 motors? i have a left and a right motor. with movement of this compass, the corresponding motor must move and the speed varies with compass angle. how can i use mapping for this? i will appreciate if you can help me write a short code for that

[@grantgupton3369]

Hey I'm not sure if you still need the help but it is actually pretty simple to control a motor. Use mapping from 0 to 255 and type in this: analogWrite(Motor, "Variable of Mapped Number"); Then wire up an N channel MOSFET with the motor wired from power to the drain pin on the MOSFET. Then attach ground to the source and attach the gate pin to the motor pin you have set. Do this for each motor and you'll be all set.

[@untrust2033]

I just get a value of 0 back on all 3 axis.

[@maxim25o2]

This is not a accelerate sensor? Behaves like it is. magnetometer sensor should work showing north pool of the earth, then Your rgb led's should show where is direction of north pool.

[@mrkiky]

That all depends on what code you put into it.

[@nettyvoyager6336]

very clever :)

[@nettyvoyager6336]

9 axis MPU 9250 6500 VCC, GND, SCL, EDA, ECL,ABO, INT, NCS, F SYNC . i have two they are only £2 each

[@nettyvoyager6336]

try a 9 axis there a fucking nightmare lol

[@prof3274]

Golly when i try to load the code there are so many errors like so many code out there why dont folks test there code on the current ide first?
