Pin Configuration

  • 5mm White LED (Pack of 10) Documentation
  • Pin Description:
  • The 5mm White LED has two pins, which are responsible for conducting electricity and facilitating the flow of current to illuminate the LED. The pins are typically labeled as Anode (+) and Cathode (-).
  • Pin 1: Anode (+)
  • Function: The anode pin is the positive terminal of the LED, which allows current to flow into the device.
  • Characteristics: The anode pin is typically longer than the cathode pin and has a smaller metal lead.
  • Connection: Connect the anode pin to the positive voltage source (e.g., VCC, 5V, or 3.3V) in your circuit.
  • Pin 2: Cathode (-)
  • Function: The cathode pin is the negative terminal of the LED, which allows current to flow out of the device.
  • Characteristics: The cathode pin is typically shorter than the anode pin and has a larger metal lead.
  • Connection: Connect the cathode pin to the negative voltage source (e.g., GND) or a resistor in your circuit.
  • Connection Structure:
  • To connect the 5mm White LED correctly, follow these steps:
  • 1. Identify the anode and cathode pins: Determine the anode (+) and cathode (-) pins by checking the length and metal lead size. The anode pin is usually longer and has a smaller metal lead, while the cathode pin is shorter and has a larger metal lead.
  • 2. Connect the anode pin: Attach the anode pin to the positive voltage source (e.g., VCC, 5V, or 3.3V) in your circuit. You can use a wire or a PCB track to make this connection.
  • 3. Add a current-limiting resistor (optional): If you're using a voltage source higher than the LED's recommended voltage, add a current-limiting resistor in series with the LED to prevent overcurrent. The resistor value can be calculated using Ohm's law and the LED's datasheet.
  • 4. Connect the cathode pin: Attach the cathode pin to the negative voltage source (e.g., GND) or the current-limiting resistor (if used) in your circuit. Use a wire or a PCB track to make this connection.
  • 5. Verify the connection: Double-check that the anode pin is connected to the positive voltage source and the cathode pin is connected to the negative voltage source or the current-limiting resistor.
  • Important notes:
  • Always handle the LED with care to avoid damaging the pins or the device.
  • Ensure the voltage and current ratings of the LED are not exceeded to prevent damage or overheating.
  • Use a suitable current-limiting resistor to prevent overcurrent, especially when using a voltage source higher than the LED's recommended voltage.
  • By following these instructions, you can properly connect the 5mm White LED in your IoT project and ensure it operates safely and efficiently.

Code Examples
### Example 1: Basic LED Control with Arduino
In this example, we will use an Arduino Uno board to control the 5mm White LED. We will connect the LED to digital pin 13 and use the `digitalWrite()` function to turn the LED on and off.
Hardware Connection:
Connect the anode (long leg) of the LED to digital pin 13 on the Arduino Uno board.
 Connect the cathode (short leg) of the LED to a 220 resistor.
 Connect the other end of the resistor to the GND pin on the Arduino Uno board.
Arduino Code:
```c
int ledPin = 13;  // Choose the pin for the LED
void setup() {
  pinMode(ledPin, OUTPUT);  // Set the pin as an output
}
void loop() {
  digitalWrite(ledPin, HIGH);  // Turn the LED on
  delay(1000);  // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);  // Wait for 1 second
}
```
### Example 2: PWM Dimming with Raspberry Pi (Python)
In this example, we will use a Raspberry Pi to control the 5mm White LED using Pulse Width Modulation (PWM). We will connect the LED to GPIO pin 18 and use the `RPi.GPIO` library to control the LED's brightness.
Hardware Connection:
Connect the anode (long leg) of the LED to GPIO pin 18 on the Raspberry Pi board.
 Connect the cathode (short leg) of the LED to a 220 resistor.
 Connect the other end of the resistor to the GND pin on the Raspberry Pi board.
Python Code:
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)  # Set GPIO pin 18 as an output
pwm = GPIO.PWM(18, 50)  # Create a PWM object with a frequency of 50Hz
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%
        pwm.ChangeDutyCycle(dc)
        time.sleep(0.1)  # Wait for 0.1 seconds
    for dc in range(100, -1, -5):  # Dim the LED from 100 to 0%
        pwm.ChangeDutyCycle(dc)
        time.sleep(0.1)  # Wait for 0.1 seconds
```
Note: Make sure to install the `RPi.GPIO` library and import it correctly before running the code.
