Pin Configuration

Component Documentation: 3mm Orange LED (Pack of 10)
Overview
The 3mm Orange LED (Pack of 10) is a standard through-hole LED component used for indicating purposes in various electronic circuits. It has a compact size of 3mm and emits an orange light.
Pin Structure
The 3mm Orange LED has two pins, which are:
Pin 1: Anode (Positive Leg)
--------------------------------
Function: The anode pin is the positive leg of the LED, which connects to the positive voltage source in the circuit.
Identification: The anode pin is usually longer than the cathode pin, making it easy to identify.
Connection: Connect the anode pin to the positive voltage source (e.g., VCC) in the circuit.
Pin 2: Cathode (Negative Leg)
-------------------------------
Function: The cathode pin is the negative leg of the LED, which connects to the negative voltage source or ground in the circuit.
Identification: The cathode pin is usually shorter than the anode pin, making it easy to identify.
Connection: Connect the cathode pin to the negative voltage source (e.g., GND) or ground in the circuit.
Connection Structure
To connect the 3mm Orange LED, follow these steps:
1. Identify the pins: Determine the anode (positive leg) and cathode (negative leg) pins of the LED. The anode pin is usually longer than the cathode pin.
2. Connect the anode pin: Connect the anode pin to the positive voltage source (e.g., VCC) in the circuit using a wire or a PCB trace.
3. Connect the cathode pin: Connect the cathode pin to the negative voltage source (e.g., GND) or ground in the circuit using a wire or a PCB trace.
4. Add a current-limiting resistor (optional): If necessary, add a current-limiting resistor in series with the LED to prevent excessive current from flowing through the LED.
Important Notes
Always ensure the correct polarity when connecting the LED to prevent damage or reverse bias.
Use a suitable current-limiting resistor to prevent excessive current from flowing through the LED, which can cause it to overheat or fail.
By following these guidelines, you can correctly connect the 3mm Orange LED (Pack of 10) in your electronic circuit.

Code Examples

### Example 1: Basic LED Blinking using Arduino

In this example, we will connect the 3mm Orange LED to an Arduino board to create a simple blinking LED circuit.

Hardware Requirements:

Arduino Board (e.g., Arduino Uno)
 3mm Orange LED
 1 k Resistor
 Breadboard
 Jumper Wires

Code:
```c
const int ledPin = 13; // Pin 13 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
}
```
Explanation: This code sets up the Arduino board to control the LED connected to pin 13. The `digitalWrite()` function is used to turn the LED on and off, and the `delay()` function is used to create a 1-second delay between each state change.

### Example 2: LED Dimming using ESP32 and PWM

In this example, we will connect the 3mm Orange LED to an ESP32 board to demonstrate LED dimming using Pulse Width Modulation (PWM).

Hardware Requirements:

ESP32 Board
 3mm Orange LED
 1 k Resistor
 Breadboard
 Jumper Wires

Code:
```c
const int ledPin = 14; // Pin 14 for the LED
int brightness = 0; // Initialize brightness to 0

void setup() {
  ledcSetup(0, 5000, 8); // Set up PWM channel 0 with 5000 Hz frequency and 8-bit resolution
  ledcAttachPin(ledPin, 0); // Attach the LED pin to PWM channel 0
}

void loop() {
  for (brightness = 0; brightness <= 255; brightness++) {
    ledcWrite(0, brightness); // Set the LED brightness using PWM
    delay(10); // Wait for 10 milliseconds
  }
  for (brightness = 255; brightness >= 0; brightness--) {
    ledcWrite(0, brightness); // Set the LED brightness using PWM
    delay(10); // Wait for 10 milliseconds
  }
}
```
Explanation: This code sets up the ESP32 board to control the LED connected to pin 14 using PWM. The `ledcSetup()` function is used to configure the PWM channel, and the `ledcAttachPin()` function is used to attach the LED pin to the PWM channel. The `ledcWrite()` function is used to set the LED brightness, and the `for` loops are used to create a fading effect.

Note: These code examples are for demonstration purposes only and may require modifications to work with your specific setup. Always ensure the LED is properly connected and powered to avoid damage.
