Description

Circuit Function:With the sound of music or other sounds, the LED lights will flash and move according to the rhythm of the sound (the speed of the sound). After successful welding, you can feel the wonderful melody combination of sound and light
Working Voltage:3-6V. When a higher working voltage is required, please add a current limiting resistor to the LED, usually ranging from tens of ohms to around 100 ohms
Circuit Principle:The voice controlled LED melody light circuit consists of a power supply circuit, a microphone amplification circuit, and an LED luminous indicator circuit. The power supply is input by JP, and C1 filtering is used for the circuit. MIC converts sound signals into electrical signals, which are coupled by C2 and amplified by Q2. The amplified signal is sent to the Q1 base electrode, where Q1 drives the LED to emit light. The louder the sound, the higher the brightness of the LED
Installation Precautions:Electret microphones can be positive or negative, and the end connected to the aluminum casing is negative. During installation, the two wires of the microphone can be threaded through the fixing holes on the circuit board and then soldered onto it, so that the wires are not easily broken. The power supply can be positive or negative, and usually connected to the power supply using a DuPont cable. You can also directly connect with a 3-6V battery pack according to the situation. The circuit adopts a bright concave infinite warm white yellow dual color LED, which can emit light both forward and backward, emitting warm white light in the forward direction and yellow light in the reverse direction. When installed, all should be in the same direction, otherwise the light may not be uniform
