High Precision Counting Scale with Arduino

From Fedeasche on Hackster.io:

I’ve worked on scale words since 2015 but the biggest challenge has always been to build something that i repair every day at work. So i decided to try it, I had an arduino UNO, a load cell and an LCD. After a long run, I decided to rely on a DFrobot hx711. After a bit of study on how to connect the converter I started writing code for calibration and for counting scale mode function using the knowledge gained at work. Surprisingly I realized I could achieve a high level of precision despite using only a cheap converter and a C3 load cell. And so after a little bit of filtering here is my ArduScale 2.0! 🙂 P.S. I have calibrated the scale with F1 class precision weights and it passed all metrological tests.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
