ESP8266 3-Color LED Module Project

The ESP8266 3-Color LED Module project showcases how to control a tri-color LED (red, green, and blue) using an ESP8266 microcontroller. This project teaches basic GPIO pin manipulation and how to mix different colors by controlling each LED independently.

Components Needed

• ESP8266 Microcontroller
• 3-Color LED Module (Red, Green, Blue)
• Jumper Wires
• Breadboard (optional)

Circuit Diagram

Circuit Setup

1.Connecting the 3-Color LED to ESP8266:

Red LED Anode (redPin): Connect to GPIO pin D5 on the ESP8266.

Green LED Anode (greenPin): Connect to GPIO pin D6 on the ESP8266.

Blue LED Anode (bluePin): Connect to GPIO pin D7 on the ESP8266.

Common Cathode: Connect to GND.

Instructions

1.Code Upload:

Open the Arduino IDE with ESP8266 board support installed.

Create a new sketch and paste the provided Arduino code.

Connect the ESP8266 to your computer, select the appropriate board and port from the Tools menu.

Upload the code to the ESP8266.

2.Testing:

After uploading the code, the LED will cycle through red, green, and blue colors, with each color displayed for 1 second.

After showing all three colors, the LEDs will turn off for 1 second before repeating the cycle.

Applications

Status Indicators: Use LEDs as visual indicators for various states in projects.

Lighting Effects: Create decorative lighting effects by mixing different colors.

Learning Platform: Experiment with basic GPIO control and color mixing on the ESP8266.

Notes

GPIO Control: The project uses digitalWrite to control the state of the GPIO pins connected to the LEDs.

delays: Delays create the color-changing effect. Adjust the delay times to change the speed of transitions.

Color Mixing: By modifying the setColor function, you can create various color combinations.
