. This allows you to test your weight scale projects without needing the physical hardware sensorsandgauges.com Download and Installation Steps Download the Library

void setup() Serial.begin(9600); pinMode(PD_SCK, OUTPUT); pinMode(DOUT, INPUT);

: Simulates variable weights using potentiometers to verify scale accuracy. Where to Download the HX711 Proteus Library

void loop() float weight = scale.get_units(5); // Average of 5 readings Serial.print("Weight: "); Serial.print(weight); Serial.println(" grams"); delay(500);

| Alternative | Pros | Cons | |-------------|------|------| | | Built into Proteus | Only 12-bit resolution | | Simulate using I2C EEPROM + Op-Amps | No download needed | Complex setup | | Use a different simulator (LTspice) | Accurate analog response | No microcontroller co-sim | | Replace with load cell amplifier (INA125) | Native Proteus model | Requires more components | | Use a pre-built Proteus project file | Plug-and-play | Hides learning details |

Load Cell Amplifier HX711 Breakout Hookup Guide - SparkFun Learn

(Clock and Data) compatible with Arduino, PIC, ESP32, etc. Built-in selectable gain (64 or 128). Why You Need a Custom HX711 Proteus Library

| Problem | Solution | |---------|----------| | Component not found after copying | Restart Proteus completely | | "Unknown part" error | Ensure both .IDX and .LIB are in the correct folder | | Simulation stuck | Add pull-up resistors (10kΩ) on DOUT and PD_SCK if needed | | No output | Check VSUP and GND connections |
