Pin Configuration

  • Component Documentation: 3mm White Green LED (Pack of 10)
  • Pin Explanation:
  • The 3mm White Green LED has two pins, which are responsible for connecting the LED to a power source and allowing it to emit light.
  • Pin 1: Anode (Positive Leg)
  • Function: Connects to the positive voltage supply
  • Identification: Typically longer than the Cathode pin
  • Color: Usually not marked with a color ring, but may have a slight bend or a smaller flat surface on the top
  • Pin 2: Cathode (Negative Leg)
  • Function: Connects to the negative voltage supply (Ground)
  • Identification: Typically shorter than the Anode pin
  • Color: Usually marked with a color ring (in this case, no color ring is specified, but it may have a rounded or a larger flat surface on the top)
  • Connection Structure:
  • To connect the 3mm White Green LED, follow these steps:
  • Step 1: Determine the polarity
  • Identify the Anode (Positive Leg) and Cathode (Negative Leg) pins based on their length and any visual cues mentioned above.
  • Step 2: Connect the Anode
  • Connect the Anode (Positive Leg) to the positive voltage supply (e.g., VCC, 5V, or 3.3V) of your circuit or microcontroller.
  • Use a suitable wire or connection method, ensuring a secure and reliable connection.
  • Step 3: Connect the Cathode
  • Connect the Cathode (Negative Leg) to the negative voltage supply (e.g., GND, 0V) of your circuit or microcontroller.
  • Use a suitable wire or connection method, ensuring a secure and reliable connection.
  • Example Connection Diagram:
  • ```

  • Important Notes:
  • Always check the recommended operating voltage and current for the LED to ensure safe and optimal operation.
  • Avoid connecting the LED directly to a power source without proper current limiting, as this can cause damage or premature wear.
  • Consider using a resistor in series with the LED to control the current and prevent overheating.
  • When handling LEDs, avoid static electricity discharge, as it can damage the component.

```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)  # Set the GPIO mode to Broadcom
led_pin = 17  # Select a GPIO pin on your Raspberry Pi
GPIO.setup(led_pin, GPIO.OUT)  # Set the pin as an output
pwm = GPIO.PWM(led_pin, 50)  # Create a PWM object with a frequency of 50Hz
while True:
    for dc in range(0, 101, 5):  # Loop through different duty cycles
        pwm.start(dc)  # Set the duty cycle
        time.sleep(0.1)  # Wait for 100ms
```
Hardware Connection
Connect the anode (positive leg) of the LED to GPIO pin 17 on your Raspberry Pi.
 Connect the cathode (negative leg) of the LED to a 220 resistor.
 Connect the other end of the resistor to GND on your Raspberry Pi.
