- With the sound of music or other sounds, LED lights follow
the rhythm of the sound (the speed of the sound) and flicker. After
successful welding, you can feel the wonderful combination of sound and
light. - Working voltage: 3-5.5V ( if you need a higher working voltage, please add a current limiting resistor on LED)
- Circuit
principle: Sound-controlled LED melody lamp circuit consists of power
supply circuit, microphone amplification circuit, LED luminous indicator
circuit, power supply by JP input, C1 filter power supply circuit. MIC
converts sound signals into electrical signals, which are coupled by C2
to Q2 amplification. The amplified signals are sent to Q1 base. Q1
drives LED to emit light. The louder the sound, the brighter the LED.
