Arduino as load cell amplifier by christian liljedahl christian liljedahl dk load cells are linear.
Mini load cell arduino.
Reload the code to the arduino board and retest your known loads.
Process for using the weighing program above.
Stacking the load cell shield the load cell shield uses analog pins a0 and a1 for strain 1 and strain 2 inputs respectively.
Arduino scale with 5kg load cell and hx711 amplifier step 1.
Restart program with nothing on the load cell platform 2.
The white connectors on the board are 4 pin molex connectors with 0 1 spacing.
Stack the load cell amplifier shield on top of the arduino board in our case a lynxmotion botboarduino.
In this project we will be interfacing hx711 load cell amplifier with arduino and 16 2 lcd for designing arduino weighing machine using load cell hx711.
Mount the load cell.
On the opposite side you can see the connection for the load cell.
Upload this sketch to your arduino board you need two loads of well know weight.
Data is extracted from a 24 bit adc on board the hx 711 ic.
Wait for tare to finish and arduino to print out.
This video will describe how to interface a 1 kg load cell to an arduino nano.
So once you have established two data pairs you can interpolate the rest.
Wait for print out.
See the wiring diagram for how to connect the load cells hx711 and arduino.
Next try an unknown load.
It is specially made for amplifying signals from cells and reporting them to another microcontroller.
In this example a 10 kg.
To connect the hx711 to the arduino you only need 2 pins clock and data.
Wire the load cells and hx711.
Open serial port 3.
Add calibrated mass 4.
Grove adc for load cell hx711 the hx711 is a precision 24 bit analog to digital converter adc that is designed for weighing scales and industrial control applications to interface directly with a bridge sensor.
We will be using a simple arduino library to communicate with the hx711 that provides a calibration and tare reset feature to easily determine the weight of an object.

Edit the values of areading aload breading and bload with those values.
First we are going to mount the load cell.
Load the above code open the serial monitor and take measurements of two known loads.
