Circuit Documentation

Summary

The circuit in question is designed around the ESP32 Wroom Dev Kit, which is a popular microcontroller with Wi-Fi and Bluetooth capabilities. The circuit includes three LEDs (red, green, and blue) each with a corresponding resistor to limit the current through the LEDs. The ESP32 is configured to control the LEDs via its GPIO pins. The ground pins of all LEDs are connected together and to the ground of the ESP32. Each LED is connected to a GPIO pin through a resistor. The absence of code suggests that the microcontroller's firmware has not been provided or is not required for this documentation.
