ESP32-Based Audio Spectrum Analyzer

A DIY audio spectrum analyzer is now achievable with an ESP32 microcontroller and a display panel, simplifying a previously complex project.

The project utilizes the CrowPanel 3.5, which integrates an ESP32 with a 480x320 touchscreen LCD. However, similar results can be achieved with other displays, potentially requiring code adjustments.

In addition to the microcontroller and display, the project requires minimal passive components to condition the analog audio signal before it is fed into the ESP32's analog-to-digital converter (ADC).
