For example, with an Arduino UNO:
Click the button at the bottom left of Proteus to start the execution. As you toggle the percentage values up and down on your POT-HG potentiometer, you should see the calculated weight values change dynamically on the virtual LCD screen. Common Troubleshooting Steps
Connect the (Data Output) pin of the HX711 to Arduino digital pin D3 .
C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY Step 3: Restart Proteus
Search for on GitHub or electronics forums. Common files include:
Navigate to your Proteus installation library folder. Typically, this is located at: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY (Note: ProgramData is a hidden folder). Restart: Restart Proteus to refresh the component library.
For , the most popular library is by Bogdan Necula, which you can install from the Arduino Library Manager.
Once installed, you can build a complete weighing scale simulation circuit using an Arduino Uno, the HX711 module, and a load cell simulator. 1. Placing Components
Connect the data and control pins of the 16x2 LCD to the Arduino digital pins (e.g., pins 4, 5, 6, 7, 8, and 9) to display the weight readings. Writing the Arduino Firmware
The microcontroller requires code to toggle the clock pin, read the 24-bit data stream from the HX711, and convert that raw data into a readable weight format. Sample Arduino Sketch

Short Verdict
To simulate an in Proteus, you must manually add the external library files to the software's directory, as Proteus does not include a ready-made load cell or HX711 model by default. 1. Download and Extract the Library
