### Example 1: Temperature Monitoring with Python
Using the included temperature sensor, this example demonstrates how to read temperature data and display it on the console.
Code:
```python
import time
import os
# Import the necessary libraries
import RPi.GPIO as GPIO
import Adafruit_DHT
# Set up the GPIO library
GPIO.setmode(GPIO.BCM)
# Define the temperature sensor pin
DHT_PIN = 4
# Set up the temperature sensor
dht_sensor = Adafruit_DHT.DHT11
while True:
# Read the temperature data
humidity, temperature = Adafruit_DHT.read_retry(dht_sensor, DHT_PIN)
# Print the temperature data
print("Temperature: {:.1f}C".format(temperature))
# Wait for 1 second before taking the next reading
time.sleep(1)
```
Output:
```
Temperature: 22.5C
Temperature: 22.6C
Temperature: 22.5C
...
```
### Example 2: Remote Video Streaming with Python and OpenCV
Using the Raspberry Pi 4's camera interface and OpenCV, this example demonstrates how to capture and stream video remotely over the network.
Code:
```python
import cv2
import numpy as np
import socket
# Set up the camera
cap = cv2.VideoCapture(0)
# Set up the socket for streaming
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(("0.0.0.0", 8080))
sock.listen(1)
print("Waiting for connection...")
conn, addr = sock.accept()
print("Connected by", addr)
while True:
# Capture a frame from the camera
ret, frame = cap.read()
# Encode the frame as JPEG
ret, jpg = cv2.imencode(".jpg", frame)
# Send the encoded frame over the socket
conn.send(jpg.tobytes())
# Check for quitting
if cv2.waitKey(1) & 0xFF == ord("q"):
break
# Release the camera and socket
cap.release()
conn.close()
```
Output:
```
Waiting for connection...
Connected by ('192.168.1.100', 52812)
```
Note: In this example, you would need to connect to the Raspberry Pi's IP address and port 8080 using a video streaming client (e.g., VLC) to view the remote video stream.
These examples demonstrate the versatility of the Raspberry Pi 4 Model B 2GB Ultimate Kit in IoT and robotics projects. With its powerful processor, abundant storage, and comprehensive bundle of accessories, this kit provides everything needed to get started with innovative projects.
