This is a project you must see. A real must see Spectrum Analyzer up to 64 Channels!!!!
64 channels, how cool is that! I am using an ESP32 and a hub75 display. The use of pixelleds WS2812 is supported as an alternative for the display.
This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.
