Scopul acestui proiect este să ofere utilizatorilor un joc Super Mario, care poate fi jucat în timpul liber. Proiectul a fost creat pentru a fi ușor de jucat și de înțeles, fiind util și pentru învățarea conceptelor hardware și software.

Proiectul m-a ajutat să aprofundez conceptele studiate la laboratoarele de PM, mai ales să înțeleg utilizarea protocolului I2C.
