+# ESP8266 RGB LED Blinking Project
+
+
+## Aim
+
+The main aim of this project is to demonstrate how to control an RGB LED using an ESP8266 microcontroller.
+
+## Purpose
+
+The purpose of this project is to provide a simple example of RGB LED control with an ESP8266, suitable for educational and learning purposes.
+
+
+## Components Required
+
+- ESP8266 microcontroller (NodeMCU)
+- RGB LED
+- Breadboard and jumper wires
+
+
+## Short description of package/script
+
+This Arduino script controls an RGB LED connected to an ESP8266 microcontroller. It uses the Adafruit NeoPixel library to cycle through red, green, and blue colors with adjustable speed.
+
+- IDE: Arduino IDE
+- Library: Adafruit NeoPixel
+
+
+## Workflow of the Project
+
+1. Initialize the NeoPixel strip.
+2. Cycle through red, green, and blue colors with a delay between each color change.
+3. Adjust the speed of color transitions by changing the `wait` value in the `colorWipe` function.
+
+
+## Setup instructions
+
+1. Connect the common cathode of the RGB LED to the ground (GND) pin on the ESP8266.
+2. Connect each RGB LED anode (R, G, B) to different GPIO pins on the ESP8266 (e.g., D1, D2, D3).
+4. Open the Arduino IDE and ensure ESP8266 board support is installed.
+4. Include the Adafruit NeoPixel library.
+5. Copy the provided code into the Arduino IDE.
+6. Replace placeholder values with actual GPIO pins.
+7. Upload the code to the ESP8266.
+
+## Detailed explanation of script
+
+The script uses the Adafruit NeoPixel library to control the RGB LED. The `colorWipe` function fills the LED with a specified color, creating a visual effect.
+
+```
+void colorWipe(uint32_t color, int wait) {
+  for(int i=0; i<strip.numPixels(); i++) {
+    strip.setPixelColor(i, color);
+    strip.show();
+    delay(wait);
+  }
+}
+```
+
+
+## Compilation Steps
+
+1. Open Arduino IDE.
+2. Set the board to ESP8266.
+3. Include the Adafruit NeoPixel library.
+4. Copy and paste the code.
+5. Replace placeholder values.
+6. Upload the code to the ESP8266.
+
+## Disclaimer
+
+Before you start making any connections please disconnect the device from your laptop/workstation so there is no power getting to the device. You should never make any connection changes when the device is powered on.
