RubyCode Examples### Example 1: Blinking LED using Python and GPIOThis example demonstrates how to use the Raspberry Pi 3B+ to control an LED connected to GPIO pin 17.
```python
import RPi.GPIO as GPIO
import time# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Set up GPIO pin 17 as an output
GPIO.setup(17, GPIO.OUT)while True:
# Turn on the LED
GPIO.output(17, GPIO.HIGH)
time.sleep(1)
# Turn off the LED
GPIO.output(17, GPIO.LOW)
time.sleep(1)
```
### Example 2: Reading Temperature and Humidity using a DHT11 Sensor and PythonThis example demonstrates how to use the Raspberry Pi 3B+ to read temperature and humidity values from a DHT11 sensor connected to GPIO pins 4 and 17.
```python
import RPi.GPIO as GPIO
import dht11# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Initialize DHT11 sensor
dht11_sensor = dht11.DHT11(pin=4)while True:
# Read temperature and humidity values
result = dht11_sensor.read()
if result.is_valid():
print("Temperature: {}C Humidity: {}%".format(result.temperature, result.humidity))
time.sleep(2)
```
### Example 3: Creating a Simple Web Server using Node.js and JavaScriptThis example demonstrates how to use the Raspberry Pi 3B+ to create a simple web server using Node.js and JavaScript.
```javascript
const http = require('http');
const url = require('url');
const fs = require('fs');http.createServer((req, res) => {
const pathname = url.parse(req.url).pathname;
if (pathname === '/') {
fs.readFile('index.html', (err, data) => {
if (err) {
console.error(err);
res.writeHead(500, {'Content-Type': 'text/plain'});
res.end('Error loading index.html');
} else {
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(data);
}
});
} else {
res.writeHead(404, {'Content-Type': 'text/plain'});
res.end('Not Found');
}
}).listen(3000, () => {
console.log('Server running on port 3000');
});
```
