Connect the RS, EN, D4, D5, D6, and D7 pins of the 16x2 LCD to your preferred digital pins on the Arduino (e.g., pins 12, 11, 5, 4, 3, 2) to monitor output. Step 4: Arduino Code

The HX711 is a 24-bit high-precision ADC designed specifically for weigh scales and industrial control applications to interface directly with a bridge sensor. In physical circuits, it amplifies the millivolt signals from a load cell and converts them into digital data.

Adjust the potentiometer value up or down. The changing differential voltages simulate load variance, and the 16x2 LCD will display the computed weight changes. If youg., 8.13, 8.15)

The directory path varies depending on your software version and system architecture:

Comprehensive Guide to the HX711 Proteus Library for Weight Sensor Simulation

The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed specifically for weigh scales and industrial control applications to interface directly with a bridge sensor. It features an onboard low-noise programmable gain amplifier (PGA), allowing it to amplify the tiny millivolt-level signals from a load cell to a measurable digital level for a microcontroller (like a PIC, AVR, or 51-family MCU).

If you had Proteus open during this process, close all instances and restart the application to force a database re-index. Setting Up an HX711 Simulation Circuit

Used to simulate the changing millivolt output of a load cell.

The HX711 communication relies on precise clock pulses. Try increasing the simulation time-step in Proteus ( Options > Simulator Options ) or remove unnecessary visual components.

The you're using (e.g., Arduino, PIC, STM32) The display type used in your schematic

Connect the pin of the HX711 to another digital pin on the Arduino (e.g., Pin 2).

If you cannot find a working HX711 Proteus library, simulate using:

Double-click the Arduino Uno component in Proteus to open the properties window. Under Program File , browse and select your generated .hex file.

The is a high-precision 24-bit analog-to-digital converter designed specifically for weigh scales and industrial control applications. It interfaces directly with a bridge sensor (load cell) to amplify and digitize the minute voltage changes caused by structural strain.

If the library fails completely, consider the alternative below.

Even with the correct library installed, users often face issues. Here are the three most common problems when using the HX711 Proteus library and how to solve them:

In this post, we provide the download link and a step-by-step guide on how to use it to simulate a Load Cell with Arduino.
