- Power supply: 5V

- Microcontroller: STC89C52

- Number of strings (beams): 7

- Size: 10cm x 5cm / 3.94in x 1.97in

Note: 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.

 

Package Included:

1 x Harp DIY Kit

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
