: Close and reopen the software to refresh the component list. If the library still doesn't appear, try running Proteus as an Administrator to bypass permission issues. Simulation Workflow
Then emulate HX711 behavior in code by applying gain and offset. This is less accurate but works for functional verification. hx711 proteus library
Practical Recommendations
. Since Proteus does not include a native HX711 component, a dedicated third-party library is required to bridge the gap between a virtual load cell and a microcontroller like Arduino. Core Components of the Simulation : Close and reopen the software to refresh
