The easy circuit demonstrates how to form one voltage divider with the ESP32 S3 microcontroller plus one 1k kiloohm resistance. Using connecting two resistors to sequence, one can reduce an electrical amount to an http://theengineerstore.in/products/12v-mini-spot-welding-machine-automatic-control-10awg-multiwire-portable-transistor-18650-lithium-battery-spot-welder
