I will keep this in mind in future videos to make sure to explain some parts. Like I did in this video explaining how to calibrate the load cell. Thank you for your comment.
@@BrainybitsCanada You could always have the main video that is nice and short, then create a separate video which just dives deeper into the code. Then when the portion about the code comes up you can link them to that video if they are interested and have them come back to finish this video after learning more about the code.
I agree. I will always take some time to explain certain parts of the code which I haven't covered in other videos. Thanks for taking the time to comment!
I will admit I skipped the coding in the middle when looking at many of your projects for the first time, BUT now that I am ready to actually do one of the projects, I am going back for the code walkthroughs. Perhaps a two-part video, one about the hardware and one about the code for each project.
Good Evening Yvan and tks for the xlnt videos. Question - how to control the speed of a stepper motor with a load cell/HX711 - (the greater the load the faster the speed). I've seen yr video on using a potentiometer to control stepper motor speed, but I can't figure out how to get an HX711 to change the speed. I'm new to this electronics malarkey. Any ideas? By the way - greetings from Glasgow, Scotland! Cheers, Miles
How about a video showing this same Load Cell setup, but with the addition of being able to set an adjustable target weight, at which point a Mosfet/relay is energized? How easy would this be to do, or have you covered this idea before?
Got mine on Amazon like this one here: www.amazon.ca/Elenco-Breadboard-Prototype-Design-Aid-9440/dp/B0002H4W0K/ref=sr_1_16?ie=UTF8&qid=1535915349&sr=8-16&keywords=breadboard Thanks for watching!
Thank you very much for the nice project. I made this and it works, but the refresh rate of the screen is very slow. Is there any way to get it any faster?
please help keeps telling me this eror and I'm not an expert on this so please help me where the error is thank you all in advance the problem is in this line help: HX711 scale(DOUT, CLK); // Init of the HX711 exit status 1 no matching function for call to 'HX711::HX711(int, int)'
Salut Yvan! J'avais un problème avec ton code de calibrage. J'utilise exactement les mêmes composantes que toi, mais j'ai reçu l'erreur HX711::HX711(int, int), alors j'ai changé le code selon une idée dans la section des commentaires de ton site web. J'ai pu calibrer. Après ça, j'ai eu un problème avec le rotary encoder qui ne fonctionnait pas correctement (quand je pesais le bouton, rien n'arrivait) donc j'ai changé ton code encore...tout "fonctionne" maintenant, mais le OLED a des caractères bizarres et le poids semble fluctuer beaucoup. Est-ce que tu as une mise-à-jour pour ton code, car je ne connais pas grand chose à l'arduino? Merci! Tu as créé exactement le projet qu'il me faut pour ma brasserie!
could I use\attach multiple independent weight sensors to a single HX711? I'm working on a project where I want to weigh half a dozen objects simultaneously, getting each objects weight?
Hello Ivan, I am trying to use your Arduino code for a project of mine but in verifying the code I'm getting an error "no matching function for call to HX711 scale(DOUT, CLK)" I don't know if there is something I am missing to download in the libraries. Please let me know as soon as you can this is important for the success of my project. :(
i do not know if you check the comments or not but im kinda suck with the code. i paired everything as you did in the video and the website but i cant get it to simulate and cant get any readings on the pc simulation or the OLED screen
Hi, i'm working on a project regarding weight monitoring. Just want to know if there are other development boards besides Arduino Uno that I can use to have the same results. Also, is it possible for me to design my own version of the HX711 signal conditioning circuit?? Thanks.
The hardest part about this is that I have a different microcontroller than the Arduino, and the code and wiring is slightly diferent, making it hard to work for me.
Would it be possible to make an alarm go off when it reaches a specific weight, and then make the alarm stop when the weight is back to the base weight?
yes it is possible check the code and write a simple "if " statement that check if the current weight is greater or equal to the weight you want the alarm to go off else alarm is off
I'm still trying to rap my head around coding. I don't have an OLED screen but I do have a 2 line LCD with I2C. Could someone please help me convert this sketch to use the LCD display?

Personally as I am not good coding, I prefer videos that explain the code as I learn from it. Thanks for the great work you do.
I will keep this in mind in future videos to make sure to explain some parts. Like I did in this video explaining how to calibrate the load cell. Thank you for your comment.
I like it when videos are split into a coarse and detailled part

In my opinion, I think it's nice to explain the important parts of the code, such as this video where you explained the calibration. Good video! :)

I prefer the detailed view I don’t mind longer videos keep up the great tutorials

Thanks! I do prefer the detailed code review, it is very helpful when troubleshooting or when altering the code.
Good day Yvan. Your new lesson format is fine with me, your line notes are quite accurate.Thank you Yvan.
Buddy I love it when you went through the code! Great video thanks for sharing!
The Awsome-O got me here. Good video!
Thanks for this, man. I learned a lot. Cool stuff
Great to hear that the videos are helping, thanks for watching!
Thanks. I was looking for info on tare and this answered my question : )

Thanks for the great video.. can u pls explainn it with multiple HX711 sensors with SD and I2C module...
How about a video showing this same Load Cell setup, but with the addition of being able to set an adjustable target weight, at which point a Mosfet/relay is energized? How easy would this be to do, or have you covered this idea before?
Hi!
Great video!! I wanted to ask if this project is possible without the display.
Is there a way for the information to appear on you PC?
Thank you!
It was a great thing explaining code.
Hi. The code looks very useful. Was the sensor 1 kg or 5 kg ?
It was a 1kg load sensor. Thanks for watching!
Thank you for your beginner friendly tutorials! One question: Where did you get this huge breadboard?
Got mine on Amazon like this one here: www.amazon.ca/Elenco-Breadboard-Prototype-Design-Aid-9440/dp/B0002H4W0K/ref=sr_1_16?ie=UTF8&qid=1535915349&sr=8-16&keywords=breadboard

please help
keeps telling me this eror
and I'm not an expert on this
so please help me where the error is
thank you all in advance
the problem is in this line
help:
HX711 scale(DOUT, CLK); // Init of the HX711
exit status 1
no matching function for call to 'HX711::HX711(int, int)'
i love it . currently making project related to it
Good luck with your project and thanks for watching!
Anyway to auto calibrate an HX711? I’m trying to use one but no way want an end user to have perform any calibration manually. Thx
Does this code uploaded directly to the HX711 or it uploaded to uno and used via the uno to give an accurate reading of the weight on the load cell?

if possible, can you please make video where you use channel A and B . one HX711 with 2 load cells

I don't have that rotary encoder . Can I complete this system without rotary encoder ? I will display the value at lcd 16x2 .
Is it possible to add load limit that can trigger a buzzer??
Do you know how to connect 2, 4 wire load cells to a single hx711?
Good guy Ivan
hi hello can you help me this error.. HX711 scale(DOUT, CLK); // Init of library ...no matching function for call to HX711::HX711(init,int)
The hardest part about this is that I have a different microcontroller than the Arduino, and the code and wiring is slightly diferent, making it hard to work for me.
What's the name of the weight sensor you used?
Would it be possible to make an alarm go off when it reaches a specific weight, and then make the alarm stop when the weight is back to the base weight?
yes it is possible check the code and write a simple "if " statement that check if the current weight is greater or equal to the weight you want the alarm to go off else alarm is off

Without 'HX711' arduino doesnt recognize signal at all?
How can I find Arduino program for it
Nice
no matching function for call to 'HX711::HX711(int, int)'
I got this error while verify the calibration code
same problem, do you get fixed?
same problem, do you get fixed?@John DaSilva
Can I get the code?
Plz make 3-Axis Camera Stabilizer with pan,tilt and role controlling
Salut yvan.
Tu devrais mettre tes codes directement en dessous du vidéo.
sir please upload the code
helo friend can you share your code
Hello you can help me? I need 100kg code !!
