# RC Car Controller Interface af42 ## Description PCB con un MCU diseñado para conectar un PC con el control de un auto RC de juguete. El MCU recibe mensajes UART del PC que indican comandos direccionales (adelante, atrás, izquierda, derecha) y activa uno de cuatro pines GPIO para simular pulsaciones de botones en el control del auto RC. ## Project Details -
