Description

Voice-activated power amplifier spectrum audio level meter LED indicator flash melody light

Description: Features:    The use of separate comparator circuits is slightly more complicated, but the structure and principle are easier to understand. With anti-reverse protection diode, it effectively prevents the polarity of the power supply from being reversed, which leads to burning the circuit and is more suitable for DIY. About signal input: The board has its own microphone, which can sense the external sound source to control the flashing of the LED lamp bead. The disadvantage is that the sensitivity is not as good as the line input, and it is easily affected by other external sounds. If line input is required, this step is about the audio signal (such as the phone headset or the computer's headphone jack). You can remove the microphone and the signal is directly introduced from the microphone. This connection is recommended. There is also a connection to the amplifier output (that is, connected to the speaker). On the basis of the previous step, a 500K or more adjustable resistor can be placed on the speaker cable. This also has disadvantages, with the volume. Increase and decrease, the number of lights will follow, and adjust the potentiometer here. LED color: red / yellow / blue / green / white / 3 colors mixed light optional; LED specification: 5MM round frosted mist Voltage: DC 5V-16V (voltage can not exceed 16v) Current: 15v voltage under 10V full brightness zui high current 200mA 5v voltage full bright current less than 50mA Board size: 100mm × 30mm;   Package Contents 100% Brand New 1 Xlevel indicator
