The easy setup illustrates how to for form an voltage circuit using the ESP32 S3 module plus a 1k Ω resistor. By connecting two resistances in series, one can lower the electrical level to the reading appropriate http://theengineerstore.in/products/12v-mini-spot-welding-machine-automatic-control-10awg-multiwire-portable-transistor-18650-lithium-battery-spot-welder
