The component is not included in the standard Proteus libraries (ISIS/Ares). Existing community-made libraries are outdated, often unstable, and incompatible with modern Proteus versions (8.x and above). For accurate simulation, users must rely on custom DLL creation , Arduino co-simulation , or hardware prototyping .
