DIY Laser Electronic Piano Kit HU-013 7 Music Scales Player Soldering Project Practice Laser Transmitters Photoresistor Receiver

1.Introduction:

HU-013 is a Laser Electronic Piano Electronic Soldering DIY Kit. It adopts the principle of laser emission and reception, and simulates strings to control and change music through laser simulation. the speaker emits the corresponding scale when the laser is blocked, which is very suitable for fun teaching and entertainment.

It is a very interesting DIY electronic product which enables users to understand the circuit more clearly and learn soldering skills.

2.Feature:

1>.Seven Musical Scale. It can simulate 7 scales do,re,mi,fa,sol,la,si.

2>.Three tones. It can switch select Treble, Alto and Bass by left button.

3>.Strum/Play Mode. Users can play music according to the music score at StrumModeor play the built-in music at Play Mode.

4>.Scale LED Indicator.the corresponding LED indicator will indicate when playing to change the scale.

5>.DIY Hand Soldering. Great for electronics hobbyists, beginners, school and home education.

4.Working Principle:

When the light beam is irradiated on the photoresistor, the resistance value is very small, the single-chip microcomputer recognizes the voltage as a low level and does not emit a tone.

When a certain beam is blocked, the resistance value of the photoresistor becomes larger, and the single-chip microcomputer recognizes the voltage as a high level, drives the speaker to emit the corresponding tone through the triode and light the LED.

5.7 String Harp DIY Kit:

The harp electronics kit exploits properties of photoresistors to play melodies with light beams instead of real strings.

When the beam strings are plucked, the corresponding LED lights will light up, and the middle, low, high three tones can be adjusted by pressing the buttons.

At the same time, there are two built-in music(Mother’s Love and Happy Birthday Song), perfect for Christmas or Birthday gifts.
