### Example 1: LED Blinking Using Python
In this example, we will demonstrate how to blink an LED connected to the Pocket BeagleBone Board using Python.
Hardware Requirements:
Pocket BeagleBone Board
 LED (any color)
 1 k resistor
 Breadboard
 Jumper wires
Software Requirements:
Python 3.x (pre-installed on the Pocket BeagleBone Board)
Code:
```python
import time
import Adafruit_BBIO.GPIO as GPIO
# Set up the LED pin as an output
GPIO.setup("P9_12", GPIO.OUT)
try:
    while True:
        # Turn the LED on
        GPIO.output("P9_12", GPIO.HIGH)
        time.sleep(1)
        # Turn the LED off
        GPIO.output("P9_12", GPIO.LOW)
        time.sleep(1)
except KeyboardInterrupt:
    # Clean up GPIO on exit
    GPIO.cleanup()
```
Explanation:
Import the necessary libraries: `time` for delay and `Adafruit_BBIO.GPIO` for GPIO access.
 Set up the LED pin (P9_12) as an output using `GPIO.setup()`.
 Use a try-except block to handle keyboard interrupts.
 Inside the loop, toggle the LED on and off using `GPIO.output()` and delay for 1 second using `time.sleep()`.
### Example 2: Reading Temperature and Humidity Using C++
In this example, we will demonstrate how to read temperature and humidity data from a DHT11 sensor using C++ on the Pocket BeagleBone Board.
Hardware Requirements:
Pocket BeagleBone Board
 DHT11 temperature and humidity sensor
 Breadboard
 Jumper wires
Software Requirements:
GNU C++ compiler (pre-installed on the Pocket BeagleBone Board)
Code:
```cpp
#include <iostream>
#include <wiringPi.h>
#include <dht11.h>
#define DHT_PIN 23 // Pin 23 for DHT11 data pin
int main() {
    wiringPiSetup();
    DHT11 dht(DHT_PIN);
while (true) {
        int temperature, humidity;
        if (dht.read(&temperature, &humidity)) {
            std::cout << "Temperature: " << temperature << "C" << std::endl;
            std::cout << "Humidity: " << humidity << "%" << std::endl;
            delay(1000); // Wait for 1 second
        } else {
            std::cerr << "Error reading DHT11 sensor!" << std::endl;
        }
    }
return 0;
}
```
Explanation:
Include the necessary libraries: `iostream` for output, `wiringPi` for GPIO access, and `dht11` for DHT11 sensor access.
 Define the DHT11 data pin (23) using `#define`.
 Use `wiringPiSetup()` to initialize the wiringPi library.
 Create a `DHT11` object with the data pin as an argument.
 Inside the loop, read the temperature and humidity data using `dht.read()` and print the values to the console.
 Use `delay()` to wait for 1 second between readings.
These examples demonstrate the versatility of the Pocket BeagleBone Board and its ability to interact with various sensors and devices. With Python and C++ programming, you can create a wide range of IoT and robotics projects with this compact and powerful board.
