// Wait for the sensor to stabilize scale.set_scale(36.059); // Calibration factor from example scale.tare(); // Reset the scale to 0 (Tare function) Serial.println("Scale Ready");

By the end, you will be able to simulate a complete digital weighing system entirely inside Proteus.
The library includes standard pins: VCC , GND , SCK (Serial Clock), DOUT (Data Out), and analog input channels A+ , A- , B+ , B- .

: Close and reopen Proteus to refresh the component database. 🏗️ Step 3: Building the Circuit
The is a custom component library for the Proteus Design Suite. It provides a visual and functional model of the HX711 breakboard.
Ensure the downloaded compressed archive contains at least two critical file types:
HX711 scale;
💡 For simulation, you can replace the real load cell with to simulate weight change.
Simulating load cells and weight-sensing projects in Proteus requires a dedicated library for the HX711 24-bit Analog-to-Digital Converter (ADC). Because Proteus does not include an HX711 model by default, installing a custom library is essential for testing weighing scales, smart bins, and industrial automation designs before hardware assembly. 1. What is the HX711 Proteus Library?
Double-check your LCD pin mappings in the Arduino code to ensure they perfectly match your Proteus schematic wiring.
Search for a (a high-precision variable potentiometer) to act as your dummy load cell sensor. // Wait for the sensor to stabilize scale
The first and most crucial question that arises when trying to find HX711 in Proteus is: "Is the HX711 Proteus library available by default?"
The HX711 Proteus library is a collection of custom simulation files ( .lib and .idx ) created by embedded system developers. It adds a virtual HX711 IC model into the Proteus ISIS workspace.
Note: The ProgramData folder is hidden by default in Windows. Enable "Hidden items" in your File Explorer View tab to see it.
