Music and electronics go together like… drum and bass. If, however you’re looking to use the ever-popular WS2812B LED strips with your install, this will normally take some medium-ish level of hacking. Such an install can be a lot of fun and/or a good learning experience
On the other hand, if you just want to start creating awesome light effects to go with your sound, then this Music Visualizer by ‘justcallmekoko’ will create analyzer-based 2-channel LED outputs by simply plugging a few things in. The device is based on the ATmega329 and uses a pair of MSGEQ7s to split the audio into seven distinct frequencies on two channels. Note that you’ll need to include the LED strip itself.
While a YouTube video is “coming soon” as of this writing, the video below details the more DIY version of this visualizer that ‘koko built in 2018. You won’t have to go through this whole process with this product, but it should give you an idea of what you can expect results-wise starting at around the 4:25 mark. More details on the visualizer board’s usage is found on GitHub.
For another take on a spectrum analyzer, we covered this Arduino Nano-based solution back in 2018!
