Arduino Scale With 5kg Load Cell and HX711 Amplifier: This Instructable describes how to make a small weighing scale using readily available off the shelf parts.Materials needed:1. Arduino - this design uses a standard Arduino Uno, other Arduino versions or clones should work also2.

Want to weigh something with uncanny precision? Use a Load Cell and an HX711 detector and you're in business! All will be explained. And it is so very easy you will be amazed.

The sketch can be found here on my GitHub: Calibration and seed-setting sketches can also be found here: The library can be found here: And if you use an Arduino Micro or Sparkfun Pro Micro what do you have to guard against if you don't want a 'bricked' Arduino? Watch to find out. Yes, it happened to me, don't let it happen to you.

And what has the postman delivered lately? A stepper motor, an Arduino Mega, an RFID. Well, watch and find out. And for the completion of the LOAD CELL project don't miss the next video part 2 which will concentrate on the way I've mounted the hardware, the software with some simple demo code - easy. That's all coming in Part 2 (video #32). Link to the load cell (500g) that I bought: As always, Thanks For Watching and don't forget to subscribe so you don't miss future episodes.

It was a challenge to put together, but everyone put in amazing contributions! Eugene: I think we did a great job! Slowdive souvlaki remastered rar download free. We had set some unusual challenges for ourselves in terms of songwriting for this album that could have derailed us, but the end result exceeded our expectations.

Memory tip: 'See' Ralph Bacon, geddit?

To start programming the Arduino, you will need to have the Arduino IDE installed from here:. Please be aware that there are some critical bugs in Arduino IDE 1.6.6. Make sure that you install 1.6.7 or higher, otherwise this Tutorial will not work! The Visuino: also needs to be installed. • Start Visuino as shown in the first picture • Click on the ' Tools ' button on the Arduino component ( Picture 1 ) in Visuino • When the dialog appears, select ' Arduino Nano ' as shown in Picture 2 Step 5: In Visuino, add and connect HX711 Weight Scale component. The first step in the calibration is to Zero the scale: • In the design area select the WeightScale1 component ( Picture 2 ) • In the Object Inspector set the value of the ' Offset ' property to minus the value from the Serial Terminal ( Picture 1 ) in my case -104216 ( Picture 2 ) • Generate, Compile, and Upload the Arduino code as you did in Step 6 • If you connect with the Serial Terminal again, you will see that the values are around Zero ( Picture 3 ) Step 9: In Visuino, set the weight scale divider for the HX711 component. The second step in calibration is to calibrate with some known weight: • Place a 1 gram weight on the sticking end of the Weight Load Cell ( Picture 1 ).

In my case I just placed a USB flash memory ( Picture 1 ) to show the process, but for real calibration you will need to place exactly one gram object. To have precise measurement you will need to mount a table on the weight cell, but I will leave you to design it yourself. There are a lot of resources on how to mechanically design scale • Connect to the Arduino with Serial Terminal ( Picture 2 ) • In the design area select the WeightScale1 component ( Picture 3 ) • In the Object Inspector set the value of the ' Scale Divider ' property to the value from the Serial Terminal ( Picture 2 ) in my case 2565 ( Picture 3 ) • Generate, Compile, and Upload the Arduino code as you did in Step 6 • If you connect with the Serial Terminal again, you will see that the values are around One ( Picture 4 ) Step 10: And play.

You have created your first Digital Scale with Arduino and HX711 ADC Weight Sensor module. Picture 1 shows the connected and powered up project.

The Video shows the running project and the serial terminal, as different weights are placed on the Load Cell. If you open the Serial Terminal in the Arduino IDE or Visuino, and there is no weight on the Load Cell, you will see values around zero displayed ( Picture 2 ) If you place some weight, you will see it displayed on the terminal ( Picture 3 ) On Picture 4 you can see the complete Visuino diagram.Also attached is the Visuino project, that I created for this Tutorial.
