Upload this code to the virtual Arduino in Proteus. Use the HX711 library by Bogdan Necula. Search for “HX711 Proteus Library” on GitHub or

#include "HX711.h"
#define DOUT  3
#define CLK   2
HX711 scale;
void setup() 
Serial.begin(9600);
scale.begin(DOUT, CLK);
scale.set_scale(2280.0);  // Calibration factor
scale.tare();             // Reset to zero
 Example source: The Engineering Projects or GitHub user:
void loop() 
float weight = scale.get_units(5);
Serial.print("Weight: ");
Serial.print(weight);
Serial.println(" g");
delay(500);

In Proteus, add a Virtual Terminal to see weight readings.
