[Feature request] - add RGB LED control on ESP32-S3 Devkit C1 (and clones) boards

[AlexC-0806]

Description:

The addition of RGB LED control to the miner software would significantly enhance the user experience, especially for those using ESP32 boards like the ESP32-S3-Devkit-C1, or its clones such as YD-ESP32-S3. This feature would allow the onboard RGB LED to provide visual feedback about the miner’s status.

Implementation Details:

The implementation of this feature is straightforward, thanks to the Adafruit NeoPixel library, which is compatible with the onboard RGB LEDs on many ESP32 boards.

Possible LED Indications:

Blue pulsing light: Indicates that the miner is running without any issues.
Red light: Signals errors, lack of Wi-Fi connection, or rejected shares.
Rainbow effect: Serves a decorative purpose, adding a cool aesthetic to the mining setup.
This feature not only adds a visual appeal to the mining setup but also provides an easy and quick way to monitor the miner’s status. It would be a valuable addition to the miner software.

Ease of Implementation:

Given the compatibility of the Adafruit NeoPixel library with the onboard RGB LEDs, implementing this feature should be relatively easy and straightforward. This library provides all the necessary functions to control the color and brightness of the LEDs, making it a perfect fit for this feature.

This feature request aligns with the goal of enhancing the user experience and the overall functionality of the miner software. It is a cool and practical addition that users would appreciate.
