Interactive Demo Program for LED Control and Sound Output Interface

This interactive demo program showcases an electronic circuit interface designed for educational purposes. It includes functionalities to control LEDs, a motor, and sound output based on button inputs. The demo involves checking button states and managing LED colors through loops, timing delays, and sound playback. With pre-defined values and motor control commands, users can visualize microcontroller capabilities in a hands-on manner. Ideal for learning programming concepts and interfacing in electronics, the program offers a practical introduction to controls and outputs.
