Circuit Documentation

Summary

This circuit consists of a 9V battery, a rocker switch, multiple LEDs of different colors (red, green, and yellow), and several resistors. The circuit is designed to light up the LEDs when the rocker switch is turned on, with each LED connected in series with a resistor to limit the current.
