Blink Controller with Color Changing

This Arduino sketch provides a versatile Blink Controller that allows you to control an LED (or an RGB LED) using serial communication. You can easily turn the LED on/off, make it blink, and change its color (for RGB LEDs) by sending specific commands via the Arduino Serial Monitor.

Features

• Turn LED On/Off: Send 'b' to turn the LED on and 'q' to turn it off.
• Blink Mode: Send 'l' to make the LED blink. The color changes while blinking.
• Color Changing (for RGB LEDs): Send 'r' for red, 'g' for green, and 'b' for blue (for RGB LEDs).
• Case-Insensitive: Commands are case-insensitive, making it user-friendly.

Getting Started

1. Hardware Setup:

   • Connect your LED (or RGB LED) to the appropriate pins on your Arduino board.
   • Ensure you have the necessary components set up for serial communication (e.g., USB cable, Arduino IDE).

2. Upload the Sketch:

   • Open the Arduino IDE, load this sketch, and upload it to your Arduino board.

3. Open the Serial Monitor:

   • Open the Arduino Serial Monitor (Tools -> Serial Monitor) or any serial communication terminal.

4. Control the LED:

   • Use the following commands to control the LED:
     • 'b' to turn it on.
     • 'q' to turn it off.
     • 'l' to make it blink with color changing.
     • 'r' for red (for RGB LEDs).
     • 'g' for green (for RGB LEDs).
     • 'b' for blue (for RGB LEDs).

5. Enjoy!:

   • Experiment with different commands and enjoy controlling your LED.

Example Usage

• To turn the LED on: Send 'b'.
• To turn the LED off: Send 'q'.
• To make the LED blink: Send 'l'.
• To set the LED color to red (for RGB LEDs): Send 'r'.
• To set the LED color to green (for RGB LEDs): Send 'g'.
• To set the LED color to blue (for RGB LEDs): Send 'b'.
