This analog spectrum analyser with 10 channels uses an analog back-end to analyse the incoming signal from line-in or microphone. The analysed signals are then transformed to a memorizing light show by the front-end ESP32
This project includes an embedded webserver to display a real time analyser on web browser capable devices in your network
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.
