51 MCU Laser Electronic Piano Electronic DIY Kit Electronic Components Welding Training Kit HU-013
Product Description: This 51 MCU laser electronic piano electronic DIY kit is a practical training kit suitable for electronic DIY enthusiasts. Through welding assembly, you can create a powerful laser electronic piano, allowing you to experience the fun of electronic music.
The kit includes all the necessary electronic components and accessories, as well as detailed assembly instructions, making it easy for you to complete the welding assembly process. The laser electronic piano uses the 51 MCU as the control core and features multiple tones and sound effects, allowing you to play a wide variety of music.
Product Specifications: Power Supply Voltage: DC 5V PCB Board Size: 98.6mm*40mm
- There are 7 strings in total, and when a string is cut, the corresponding pitch is emitted from the speaker.
- The LED corresponding to the cut string lights up when the string is cut.
- Three types of tones (high, medium, and low) can be switched by buttons.
- Two stored songs can be played by buttons (“Happy Birthday” and “Mother”).
The PCB board is marked with various component indicators. Pay attention to the corresponding directions when welding according to the markings on the PCB board. The laser harp only needs to wave the string beam to play a melody. Consists of a photoresistor and STC89C52. The resistance of the photoresistor decreases as the light intensity increases and increases as the light intensity decreases. When the laser beam shines on the photoresistor, the resistance value of the photoresistor is very small. The MCU recognizes this voltage as a low level and does not emit a pitch. When a certain value of the laser harp string is blocked, the resistance of the photoresistor receiving the blocked light decreases, and the resistance value increases. The MCU recognizes this voltage as a high level, drives the speaker to emit the corresponding pitch through the transistor, and lights up the corresponding LED.
