I started looking into using a Pro Micro with an MSGEQ7 to process audio to make LED light strips change with music. I’ll need an input source as well as capacitors and resistors which I’ve ordered via Aliexpress. It will take a long time for those to arrive, but the cost savings is considerable. An MSGEQ7 is priced at $12 on Amazon and $1.17 on Aliexpress. #Microcontroller#ProMicro
