## Description

Circuit function:As the music or other sounds sounded, the LED lights shone with the rhythm of the sound (the speed of the sound). After the welding is successful, you can feel the beautiful melody of sound and light.Operating Voltage:3-4.5V, when higher operating voltage is required, add current limiting resistor on the LED, generally several tens of ohms to 100 ohms or so.Circuit principle:Voice-activated LED melody lamp circuit consists of power circuit, microphone amplifier circuit, LED light instruction circuit, the power input by the JP, C1 filter circuit for use. The MIC converts the sound signal into an electrical signal, which is amplified by the C2 coupling to Q2. The amplified signal is sent to the base of Q1, which is driven by Q1 to emit light. The louder the sound, the higher the LED brightness.Installation Notes: Electret microphones have positive and negative points, and the aluminum shell is connected to the negative end. Use the cut-out resistor to solder the poles of the microphone during installation, and then install it on the circuit board. There are positive and negative power supply, the general use DuPont line to connect the power supply. Can also be directly connected with 3-4.5V battery box according to the situation.Packing:5pcs led kits
