🌈 Unlock Limitless Creative Possibilities with Sparkfun Spectrum Shield Review

This sign took my project from cool to amazing. The only small issue is the lack of community code samples, but that's not a problem for Sparkfun itself. Now I have the coolest light parties in town! I recommend this product to anyone who thinks they might need it. This is a worthwhile investment and a very cool product!

I'm using this for an Arduino project to sync lights to sound. This allows me to capture different ranges of sound, allowing me to sync bass and treble separately. All in all, it's pretty easy to use. Sparkfun has sample code online that should get you started pretty quickly if you're familiar with software development. Ranges aren't as narrow as we'd like; there seems to be quite a bit of overlap. And the gain also seems to be slightly different on each band, which I was able to accommodate in

Nice and easy way to get spectral audio content in Arduino. It uses a pair of ASICs that look at the spectrum of a line-level audio source (such as a headphone jack) and sample the audio spectrum on the stereo channels. This is combined into 7 frequency slots per channel. When the ASIC hits the clock pin with a digital line pulse, it sends an analog signal proportional to the amplitude of the audio content in that band to the Arduino's audio input - since it's stereo, it uses two audio inputs…
