The easy circuit demonstrates the way for build an electrical divider by an ESP32 S3 module and the 1k Ω resistance. With connecting dual resistances on order, you can are able to reduce the voltage level into an value http://theengineerstore.in/products/12v-mini-spot-welding-machine-automatic-control-10awg-multiwire-portable-transistor-18650-lithium-battery-spot-welder
