Circuit Documentation

Summary of the Circuit

This circuit appears to be a simple LED control circuit that uses a potentiometer to adjust the brightness of the LED, a rocker switch to turn the LED on and off, and a resistor to limit the current through the LED. The circuit is powered by a 9V battery. There is no microcontroller or embedded code involved in this circuit.
