GPIO.setmode(GPIO.BCM)
# Set up Pin 17 as an output
GPIO.setup(17, GPIO.OUT)
try:
    while True:
        # Blink the LED
        GPIO.output(17, GPIO.HIGH)
        time.sleep(1)
        GPIO.output(17, GPIO.LOW)
        time.sleep(1)
except KeyboardInterrupt:
    # Clean up GPIO when exiting
    GPIO.cleanup()
```
Example 2: Node.js Script for Web Interface
In this example, we'll create a simple web interface to control the Raspberry Pi's GPIO pins using Node.js and the Express.js framework.
Hardware Requirements:
Raspberry Pi 4 Model B 4GB Ram Desktop Kit
 Breadboard
 LED
 220 resistor
 Jumper wires
Node.js Code:
```javascript
const express = require('express');
const app = express();
const gpio = require('rpi-gpio');
// Set up GPIO mode
gpio.setup(17, gpio.DIR_OUT);
app.get('/', (req, res) => {
  res.send(`
    <html>
      <head>
        <title>Raspberry Pi GPIO Control</title>
      </head>
      <body>
        <h1>Raspberry Pi GPIO Control</h1>
        <form>
          <input type="submit" value="Toggle LED" />
        </form>
      </body>
    </html>
  `);
});
app.post('/toggle', (req, res) => {
  // Toggle the LED
  gpio.write(17, gpio.HIGH);
  setTimeout(() => {
    gpio.write(17, gpio.LOW);
  }, 1000);
  res.send('LED toggled!');
});
app.listen(3000, () => {
  console.log('Server started on port 3000');
});
```
Note: Make sure to install the `rpi-gpio` package using `npm install rpi-gpio` before running the Node.js script.
These examples demonstrate the Raspberry Pi 4 Model B 4GB Ram Desktop Kit's versatility in various contexts, from simple GPIO control to web-based interfaces.
