Circuit Documentation
Summary of the Circuit
This circuit is designed around the ESP32 microcontroller, which is intended to control two red LEDs through its GPIO pins. The ESP32's digital pins D26 and D27 are used to drive the LEDs via current-limiting resistors. The ground (GND) pin of the ESP32 is connected to the cathodes of both LEDs, establishing a common ground for the circuit. The resistors are in place to limit the current flowing through the LEDs, protecting them from damage due to overcurrent.

Documented Code
No code has been provided for the microcontroller. The ESP32 would typically be programmed to control the state of the GPIO pins D26 and D27 to turn the LEDs on and off. Since no code is available, it is assumed that the user will develop the necessary firmware to control the LEDs as per the requirements of their application.
