Pin Configuration

5mm White Blue LED (Pack of 10) Pinout and Connection Guide
The 5mm White Blue LED is a standard LED component used in various IoT and electronics projects. This documentation explains the pinout and connection guide for the LED.
Pinout:
The 5mm White Blue LED has two pins:
1. Anode (Positive Leg): The longer leg of the LED, usually marked with a + sign or a small triangle on the LED body.
2. Cathode (Negative Leg): The shorter leg of the LED, usually marked with a - sign or a flat edge on the LED body.
Connection Guide:
To connect the 5mm White Blue LED, follow these steps:
Step 1: Identify the Pins
Identify the Anode (Positive Leg) and Cathode (Negative Leg) pins on the LED.
The Anode is usually longer and has a + sign or a small triangle on the LED body.
The Cathode is usually shorter and has a - sign or a flat edge on the LED body.
Step 2: Connect the Anode to the Power Source
Connect the Anode (Positive Leg) to the positive voltage source (VCC) or the collector of a transistor (if using).
Ensure the voltage source is within the recommended operating voltage range for the LED (usually 2-3.5V).
Step 3: Connect the Cathode to the Ground or Resistor
Connect the Cathode (Negative Leg) to the ground (GND) or a current-limiting resistor (if using).
The resistor is required to limit the current flowing through the LED and prevent damage.
Step 4: Verify the Connection
Verify the connections to ensure the Anode is connected to the positive voltage source and the Cathode is connected to the ground or resistor.
Double-check the polarity of the LED connections to avoid damage.

Code Examples

### Example 1: Basic LED Toggle with Arduino

In this example, we'll use an Arduino board to toggle the LED on and off.
```cpp
const int ledPin = 13;  // Choose a digital pin on your Arduino board

void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  digitalWrite(ledPin, HIGH);  // Turn the LED on
  delay(1000);
  digitalWrite(ledPin, LOW);   // Turn the LED off
  delay(1000);
}
```
### Example 2: PWM Dimming with Raspberry Pi (Python)

In this example, we'll use a Raspberry Pi to dim the LED using Pulse Width Modulation (PWM).
```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)  # Choose a GPIO pin on your Raspberry Pi

pwm = GPIO.PWM(18, 50)  # Create a PWM object with a frequency of 50 Hz
pwm.start(0)  # Start the PWM with a duty cycle of 0%

while True:
    for dc in range(0, 101, 5):  # Dim the LED from 0% to 100% duty cycle
        pwm.ChangeDutyCycle(dc)
        time.sleep(0.1)
```
### Example 3: LED Flasher with ESP32 (MicroPython)

In this example, we'll use an ESP32 board to create a simple LED flasher using MicroPython.
```python
import machine
import utime

led = machine.Pin(2, machine.Pin.OUT)  # Choose a GPIO pin on your ESP32 board

while True:
    led.value(1)  # Turn the LED on
    utime.sleep(0.5)
    led.value(0)  # Turn the LED off
    utime.sleep(0.5)
```
Remember to adjust the pin connections and voltage levels according to your specific setup and requirements.
