ESP32 I2s audio project for internet radio streaming via WiFi.
Includes a volume control potentiometer, channel navigation buttons, and a set of audio URLs for internet musical content as well as system testing.
Note: The ESP32 ADC (Analog to Digital Converter) pins, by default, can measure voltage in the range of 0V to 3.3V. This is because the ESP32 operates at 3.3V.
