-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-DinnerRecv is an Arduino project for a FireBeetle 2 ESP32-E microcontroller that controls a WS2812B LED strip. The project creates a sequential white light animation across 8 LEDs.
-
-## Hardware Configuration
-
-- **Microcontroller**: FireBeetle 2 ESP32-E
-- **LED Strip**: WS2812B (8 pixels)
-- **Data Pin**: GPIO 16
-- **Power**: 5V from bottom of the board (under USB connector)
-- **Resistor**: 470 Ohm between data line and LED strip
-
-## Development Environment
-
-This is an Arduino sketch (.ino file) that should be developed using:
-- Arduino IDE
-- PlatformIO
-- Or other Arduino-compatible development environment
-
-## Key Dependencies
-
-- `Adafruit_NeoPixel` library for WS2812B LED control
-
-## Code Architecture
-
-The code follows standard Arduino structure:
-- `setup()`: Initializes serial communication (115200 baud) and LED strip
-- `loop()`: Continuously runs the LED animation sequence
-
-## Hardware Reference
-
-Implementation follows the tutorial at: https://esp32io.com/tutorials/esp32-ws2812b-led-strip
-
-## Configuration Constants
-
-- `PIN 16`: Data pin for LED strip
-- `NUMPIXELS 8`: Number of LEDs in the strip
-- `DELAYVAL 50`: Delay in milliseconds between LED updates
