- Using a 1kg load cell, HX711 amplifier chip, and an ATmega328P I create a kitchen scale.

Cool project 👍
Hello, the right project I was looking for. Will be using it to weight wild birds when they land on a dish with seeds . Two questions if I may: 1) About the two push-buttons, the one in pin 1 of the ATMega is the reset, the other on pin 16 (PB2) is it the Tara?
2) Is it OK to use pins 8 and 22 for a ground bus? Or it is only to show on the diagram.
can your calibration code for this be used on a 50kg load cell? the ones that look like a square?
Hello sir, how do you tare it ?
hello sir... ca you help me for my laod cell i dont know how to use it. My load cell is 200 kg maximum.
I'd love to learn how to build this! Do you offer private lessons
Can I use an Arduino nano esp32-s3 for this?
👍👍👍
How do you make your wiring diagrams? They are so beautiful especially for smaller circuits.

Cool video! I want to build a scale for my beehives, but I don't want to have them powered on constantly as I will really only need to check the weight weekly. Will the scale always show zero then when I switch it on or can I write the code so that it only tares once and then from that point on always displays the load? Is my question clear?
Yes, the scale will always show zero when turned on. If left on for a long time the measurement may drift by a few grams, this is not a precision device, merely a fun hobby project. I am not sure what you mean in the second half of the sentence "can I write the code so that it only tares once and then from that point on always displays the load".
Note that you will be able to find cheaper and more precise scales from manufacturers, but if your application is just for fun and learning then definitely make your own!
@@WillDonaldson thanks. I don't understand why zero will be displayed when applying load and then switching on the power. I thought that during calibration the factor is saved and will be applied on the values received by the amplifier. The arduino code could use that value each time the device is powered on. I will still try to figure it out. Thanks again for the great video.
Hello,
Thank you for this video
Please can you help me solve my problems about my Arduino project
Sincerely 🙂 🙂
yes.
I enjoyed your video :) Keep it up! Would you like to be RUclips friends? :)
