+
+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
