• Led Module for Acoustic Sensing Spectrum Audio Power Amplifier Level Meter Led Indicator Flash Melody Light Sound Partner Feature :1. Using fantastic materials, product fine is guaranteed2. Exquisite appearance, 5MM round head mist LED, the sunshine is uniform and never dazzling3. Product signal sensitivity is adjustable4. The product comes with an anti-reverse protection diode, that may effectively prevent the circuit from being burned due to opposite polarity of the flexibility supply, and is more well suited for DIY5. Wide vary of applications, used in various advertisement events Product parameters:Lamp bead: 5MM round fog LEDPower supply: between DC 5V~12VThe board comes with a MICROUSB socket, which are plugged in with the corresponding mobile phone charging cable for energy supply, and a couple of pad ports are reserved for the benefit of the man to steer the wireThe signal sensitivity is adjustable, and the onboard adjustable potentiometer can be adjusted for about ten circles. When you regulate it to the end, you should pay attention a ticking sound contained in the potentiometer. Counterclockwise capacity to decrease, and clockwise skill to increase. Precautions:The louder the sound, the additional LED lighting fixtures up from bottom to top. With the ups and downs of the sound, the LED will also soar with the music, particularly when gambling DJ. Using an independent comparator circuit is slightly complicated, however the structural precept is less complicated to understand. Regarding the signal input: the board comes with a microphone, which does not should be connected to an audio signal. It can sense and get preserve of an exterior sound source to administer the flickering of the LED mild beads. The disadvantage is that the sensitivity is not nearly as good because the line input, and it is easily suffering from different outside sounds. If line enter is required, this step is ready the audio sign (such since the headphone jack of a cellphone or computer, which can't be connected to the output of the ability amplifier or the speaker), you would eliminate the microphone, and the sign is immediately imported from the microphone. If the lighting are all on , then regulate the potentiometer (decrease counterclockwise) to put forward this connection. Package list:Audio Level Meter*1
