DIY Electronic Kit - Voice Activated LED Light - Soldering Project - Teaching

Product Description

The louder the sound, the LED will jump with the music as the sound rises and falls, making it even more interesting to play the DJ. Using an independent comparator circuit is slightly more complicated, but it can be displayed accurately. With an anti-reverse protection diode, it can effectively prevent the circuit from being burned due to the reverse polarity of the power supply, which is more suitable for DIY.
