Product parameters:
1, Size: length 10cm* width 3cm;
2, lamp bead :5mm round head fog LED, light uniform not dazzling (multicolor optional);
3, Power supply: DC between 5V~12V, the board comes with a microUSB socket, you can use the corresponding mobile phone charging cable to plug in the power supply, also reserved 2 welding tray port, convenient for users to lead;
4, the signal sensitivity is adjustable, the on-board adjustable potentiometer, can be adjusted about ten turns, tuning in the end can hear the potentiometer inside the ticking sound, counterclock to reduce, clock-to-increase;
The louder the sound, the more the LED lights up from the bottom up. With the ups and downs of the sound, the LED will also jump with the music, especially when the DJ is playing.
The independent comparator circuit is a little more complicated, but its structure and principle are easier to understand.
With anti-reverse connection protection diode, effectively prevent power polarity reverse connection caused by burning circuit, more suitable for DIY.
About the signal input: the board comes with a microphone, do not need to connect the audio signal, can induction receive external sound source control LED light bead flashing, the disadvantage is that the sensitivity is not as good as the line input, easy to be affected by other external sound.
If you need line input, this step is talking about audio signal (such as mobile phone or computer headphone hole is, can not be connected to the output of the power put or on the horn), you can take out the microphone, the signal is directly introduced from the microphone, if the lamp is all bright, then adjust potentiometer (reduce the counter clock) recommend this kind of connection.
