Circuit Documentation

Summary

This circuit is designed to control multiple high-power LEDs using an ESP32 microcontroller and N-Channel Power MOSFETs. The circuit includes resistors to limit current and a 12V battery to power the LEDs. The ESP32 microcontroller is used to control the gates of the MOSFETs, which in turn control the LEDs.
