This simple circuit illustrates how for form one potential divider using an ESP32 S3 processor plus a 1k Ω resistance. Using placing pair of resistors in sequence, you may decrease a electrical amount for the value http://theengineerstore.in/products/10w-15w-20w-stereo-bluetooth-amplifier-board-12v-24v-digital-power-amplifier-module-xy-p15w
