what screen did you use?
Give the coding please
Need a code program please😢
Good video. I suggest, however, that you use a more solid base, such as aluminum or even steel, instead of plastic. The flexing and bending of the plastic will cause inaccuracies in weighing. For demo purposes, your setup is fine but if you don't mention that a solid base is required, anyone who might still be learning will not get that important piece of knowledge.
Thanks for the great content, if I am getting negative from my sensor whar could be wrong
Hi, on your website "how to power an arduino", please do a VERY important addition. You need to note that the "Arduino Nano EVERY", that exact model, should not be powered through the 5V pin. Please add this crucial info so people dont damage their nano every.
Hey! Can you give a source for it so I can link back to the explanation of why it can't be done? Powering it via USB will also connect 5V from the USB directly to the Arduino bypassing the VIN pin's regulator. What is the fundamental difference that makes powering it from the 5V pin damaging to the Arduino?

Hi Luuk, I'm looking for analyzing video data from a Camera to use it in a home made spectrophotometer, so I would know if is possible not just to display video image captured on a window, but rather logging each single video data byte from Camera to analyze it by arduino itself or eventually by PC. Thanks a lot for your any information, and congratulation for your very good explanation of all your projects. Andrea (from Rome, Italy)

I’m just trying to do this exact thing, but with a raspberry pi
Hello, I have a few boards from this company (1kg, 5kg, maybe 10kg) and I'm wondering if the same HX711 board will work for all of them, (ie: the boards are identical) or if each load type needs the specific board that came in the package. (I'm trying to make a device that can swap out load cells, so it'd be convenient to not have to swap the board as well.)
So the code used for uno can also be used for mega? Do I have to modify anything on the given code you provided on github? Or can just upload right away to the arduino mega board??

I will program an Arduino Uno using a load cell with HX711. Initially, I place a 50-gram weight on the load cell, which has been calibrated with a float calibration factor of -1694.10, and the relay is off initially. The program will run in a loop 5 times, where in each iteration, the weight reduction should only be between 8-12 grams. If the reduction exceeds this range, the relay will turn on, and this process will continue for 5 iterations. Please help me

hello, my 1 bathroom type load cell output value keep on varing, first increase and then decrease. why please help what to do?
If the input to loadcell is consistant and the output is varying then the loadcell is bad. This is with no load change I assume.
Is there an example of it in any simulation circuit? Or I can do it in a simulation program
That's a brilliant demo, Mate! Thanks.

Hi Indrek, I like your videos very much. Can we get in touch? I'm a hobbyist as well as it concerns Arduino and 3D-printing. I have some challenges!
I added 1 component to the circuit and could do away with the Arduino, exactly what I was looking to do! Thanks again Indrek
Hello Indrek How are you..... Suppose we want to use long wires between load cell and hx711 what type of capacitor further to add to boost signal ...wire lenth 2m approx ??
No need for capacitor. The lenght of the wire between load cell and hx711 must be small to avoid electro-magnetic interferences that will add noise
Okay But suppose we need to place Main Arduino board a further away from load cell what are the options as in we cannot increase distance between Arduino and HX711 connections ? Only option is to increase distance between load cell and hx711 ?
