The project demonstrates low-level hardware abstraction by interfacing with an onboard 12-bit SAR ADC for thermal monitoring and utilizing a General Purpose Timer for precise LED toggling. Furthermore, the entire hardware environment is successfully virtualized and tested using the <strong>Renode</strong> simulation framework.</p>
