RGB LED (Common Cathode - Clear) (Pack of 10)
RGB LED (Common Cathode - Clear) (Pack of 10)
The RGB LED (Common Cathode - Clear) is a type of light-emitting diode (LED) that emits a combination of red, green, and blue light to produce a wide range of colors. This component is commonly used in various Internet of Things (IoT) projects, robotics, and electronic devices that require colorful visual indicators or displays.
| The RGB LED (Common Cathode - Clear) is a multi-color LED that can produce up to 16,777,216 different colors by varying the intensity of the red, green, and blue light. The LED has four pins | one common cathode (negative leg) and three anodes (positive legs) for the red, green, and blue light sources. By applying different voltage levels to the anodes, the LED can produce a wide range of colors, from pure red, green, and blue to various shades of yellow, orange, purple, and white. |

Pin 5: Common CathodeCode Examples### Example 1: Basic RGB LED Control with ArduinoThis example demonstrates how to control the RGB LED using an Arduino board. It sets the LED to display a bright red color.```arduino
const int redPin = 9; // Pin 1 of the RGB LED
const int greenPin = 10; // Pin 2 of the RGB LED
const int bluePin = 11; // Pin 3 of the RGB LEDvoid setup() {
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
}void loop() {
// Set the LED to bright red
digitalWrite(redPin, HIGH);
digitalWrite(greenPin, LOW);
digitalWrite(bluePin, LOW);
delay(1000); // Wait for 1 second
}
```### Example 2: Fading RGB LED with Raspberry Pi (Python)This example demonstrates how to fade the RGB LED using a Raspberry Pi and Python. It gradually changes the LED's color from blue to red.```python
import RPi.GPIO as GPIO
import time# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
red_pin = 17
green_pin = 23
blue_pin = 24
GPIO.setup(red_pin, GPIO.OUT)
GPIO.setup(green_pin, GPIO.OUT)
GPIO.setup(blue_pin, GPIO.OUT)# Define a function to set the LED color
def set_color(red, green, blue):
GPIO.output(red_pin, GPIO.HIGH if red else GPIO.LOW)
GPIO.output(green_pin, GPIO.HIGH if green else GPIO.LOW)
GPIO.output(blue_pin, GPIO.HIGH if blue else GPIO.LOW)try:
while True:
# Fade from blue to red
for i in range(100):
set_color(i % 2, 0, (100 - i) % 2)
time.sleep(0.01)
except KeyboardInterrupt:
GPIO.cleanup()
```### Example 3: RGB LED Color Cycling with ESP32 (MicroPython)This example demonstrates how to cycle through different colors using an ESP32 board and MicroPython.```python
import machine
import utime# Set up GPIO pins
red_pin = machine.Pin(18, machine.Pin.OUT)
green_pin = machine.Pin(19, machine.Pin.OUT)
blue_pin = machine.Pin(20, machine.Pin.OUT)# Define a function to set the LED color
def set_color(red, green, blue):
red_pin.value(red)
green_pin.value(green)
blue_pin.value(blue)while True:
# Cycle through colors
set_color(1, 0, 0) # Red
utime.sleep(0.5)
set_color(0, 1, 0) # Green
utime.sleep(0.5)
set_color(0, 0, 1) # Blue
utime.sleep(0.5)
set_color(1, 1, 0) # Yellow
utime.sleep(0.5)
set_color(1, 0, 1) # Magenta
utime.sleep(0.5)
set_color(0, 1, 1) # Cyan
utime.sleep(0.5)
```Remember to adjust the pin connections and voltage levels according to your specific board and setup.
