5mm Round Red Diffused LED (Pack of 10) Documentation
Overview
The 5mm Round Red Diffused LED is a standard LED component used in various IoT applications, including robotics, automation, and general lighting. This documentation provides a detailed explanation of the pins and their connections.
Pin Structure
The 5mm Round Red Diffused LED has two pins, as shown below:
Pin 1: Anode (Positive Leg)
Pin Location: Longer leg
Function: The anode is the positive terminal of the LED, responsible for receiving the positive voltage supply.
Connection: Connect the anode to the positive voltage source (VCC) or the collector of a transistor (if used as a switch).
Pin 2: Cathode (Negative Leg)
Pin Location: Shorter leg
Function: The cathode is the negative terminal of the LED, responsible for sinking the current to the ground.
Connection: Connect the cathode to the ground (GND) or the emitter of a transistor (if used as a switch).
Connection Structure
To connect the 5mm Round Red Diffused LED:
1. Connect the Anode (Longer Leg) to:
VCC (Positive Voltage Supply) if using a voltage source directly.
Collector of a transistor (e.g., NPN or PNP) if using as a switch.
2. Connect the Cathode (Shorter Leg) to:
GND (Ground) if using a voltage source directly.
Emitter of a transistor (e.g., NPN or PNP) if using as a switch.
Important Notes:
Always check the datasheet of the specific LED component for any variations in pin structure or connection requirements.
Ensure the LED is connected with the correct polarity to avoid damage or reversed voltage.
Use a current-limiting resistor in series with the LED to prevent overheating and prolong its lifespan.
Use a suitable voltage source and current rating for the LED, as specified in the datasheet.
By following these guidelines, you can properly connect and utilize the 5mm Round Red Diffused LED in your IoT projects.

5mm Round Red Diffused LED (Pack of 10) Documentation

Overview

The 5mm Round Red Diffused LED is a high-brightness, low-power LED component commonly used in various IoT projects, including indicator lights, status indicators, and decorative lighting. This documentation provides a comprehensive guide to using this component in your IoT projects, along with code examples in popular programming languages.

Specifications

LED Type: 5mm Round Red Diffused
 Package: Pack of 10
 Forward Voltage: 1.8-2.2V
 Forward Current: 20mA
 Luminous Intensity: 100-150mcd
 Viewing Angle: 60
 Operating Temperature: -25C to +85C

Pinout

The 5mm Round Red Diffused LED has two pins:

Anode (Positive): Longer leg
 Cathode (Negative): Shorter leg

Connecting the LED

To use the LED, connect the anode (positive) leg to a voltage source (e.g., a microcontroller's digital output) and the cathode (negative) leg to ground or a resistor, depending on the circuit design.

Code Examples

### Example 1: Blinking LED with Arduino

```c
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); // Wait 1 second
  digitalWrite(ledPin, LOW); // Turn the LED off
  delay(1000); // Wait 1 second
}
```

In this example, we connect the LED's anode to digital pin 13 on an Arduino board and the cathode to ground through a 220 resistor (not shown in the code). The `digitalWrite()` function is used to toggle the LED on and off.

### Example 2: Controlling LED Brightness with Raspberry Pi (Python)

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT) // Choose a GPIO pin on your Raspberry Pi

try:
    while True:
        for brightness in range(0, 101, 10): // Change brightness from 0 to 100%
            GPIO.PWM(17, 50).start(brightness) // Set PWM frequency to 50Hz
            time.sleep(0.1) // Wait 100ms
except KeyboardInterrupt:
    GPIO.cleanup()
```

In this example, we connect the LED's anode to GPIO pin 17 on a Raspberry Pi and the cathode to ground through a 220 resistor (not shown in the code). We use the `RPi.GPIO` library to create a PWM (Pulse-Width Modulation) signal to control the LED's brightness.

Additional Notes

When using the LED in a circuit, ensure the voltage and current ratings are not exceeded to prevent damage to the component.
 A suitable resistor should be used in series with the LED to limit the current and prevent overheating.
 The LED's viewing angle and luminous intensity may vary depending on the application and environmental conditions.
