Can be placed near the sound system, you can feel the wonderful melody combination of sound and light, and let the light dance with the music!

2. Feature:
  The louder the sound, the brighter the LED
  A small and cheap kit to practice your soldering skills
and learn basic electronics knowledge and troubleshooting a circuit.
  This Soldering Practice Kit is simple, suitable for children and electronic beginners to practice soldering. A good father-son time diy project at home.

  1>.Work Voltage:DC 3-5.5V
  2>.Work Temperature:-25℃~85℃
  3>.Work Humidity:5%~95%RH

3.Common problem:
  1>.The positive and negative electrodes of the LED are not noticed, and the long leg is the positive electrode.
  2>.If the three resistors are not welded according to the identification on the board, use a multimeter to measure or read the resistance color ring.
  3>.The triode was not inserted according to the shape on the board, resulting in incorrect orientation.
  4>.The positive and negative electrodes of the microphone are not aligned, and the long pin positive electrode or the pin connected to the housing is the negative electrode.
  5>.The capacitance of electrolytic capacitor is soldered incorrectly, one is 1uf, and the other is 47uf. Pay attention to distinguishing between them. Long pin positive electrode.
  6>.The positive and negative electrodes of the power supply are connected reversely, subject to the identification on the board. The line corresponding to the+sign is the positive electrode, and the line corresponding to the - sign is the negative electrode.
  7>.Check for welding short circuits and faulty soldering. The power supply voltage is 3-5.5V, and a stable power supply is required. It is best to use batteries for power supply.
