A easy circuit shows how to for build a voltage circuit using the ESP32 S3 processor & a 1k ohm resistor. With placing pair of resistances to series, one may decrease a potential level to the value suitable to sensing http://theengineerstore.in/products/2-80w-100w-bluetooth-5-0-aptx-hd-tpa3116d2-power-amplifier-board-2-1-tpa3116-pcm5102a-dac-audio-ne5532-equalizer-class-d-amp
