Features:

1. High Bass Switch: Easily toggle between high and low frequencies to enjoy a versatile range of musical tones suitable for different melodies.

2. Pre-Programmed Songs: Comes with two pre-stored melodies that can be played with a simple button press, making it convenient to demonstrate the harp's capabilities.

3. Illuminated Strings: The seven beams of light serve as virtual strings, each illuminating a corresponding LED when their beam is interrupted. This visual cue enhances the interactive experience.

4. Interactive Sound Generation: Each of the seven strings produces a specific audible note when the corresponding light beam is interrupted, replicating the interactive nature of traditional harps.

5. Precision Sensor Technology: Utilizes photosensitive resistors to detect light interruptions, which are then processed by the microcontroller to generate corresponding sound frequencies within the audible range.
