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
