STC89C52 Electronic Harp Interactive Sound Generation High Bass Switch Illuminated Strings Precision Sensor Technology 7

Specifications:- Power supply: 5V- Microcontroller: STC89C52- Number of strings (beams): 7- Size: 10cm x 5cm / 3.94in x 1.97inNote: This is a DIY kit and requires soldering by yourself. 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.
