Code Examples
### Example 1: Basic Python Script to Blink an LED
This example demonstrates how to use the GPIO pins on the Raspberry Pi 4 board to blink an LED.
Hardware Requirements:
1x LED
 1x 220 resistor
 1x Breadboard
 Jumper wires
Software Requirements:
Raspbian operating system
 Python 3.x installed
Code:
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Set up LED pin as output
GPIO.setup(17, GPIO.OUT)
while True:
    # Turn LED on
    GPIO.output(17, GPIO.HIGH)
    time.sleep(1)
    # Turn LED off
    GPIO.output(17, GPIO.LOW)
    time.sleep(1)
```
Explanation:
This code uses the RPi.GPIO library to access the GPIO pins on the Raspberry Pi 4 board. It sets up pin 17 as an output and then enters an infinite loop, toggling the LED on and off every second.
### Example 2: Home Automation using Python and GPIO
This example demonstrates how to use the Raspberry Pi 4 board to control a relay module and automate a home appliance.
Hardware Requirements:
1x Relay module (e.g., SRD-05VDC-SL-C)
 1x Home appliance (e.g., lamp)
 Jumper wires
Software Requirements:
Raspbian operating system
 Python 3.x installed
Code:
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Set up relay pin as output
GPIO.setup(23, GPIO.OUT)
while True:
    # Turn relay on (turn lamp on)
    GPIO.output(23, GPIO.HIGH)
    time.sleep(5)
    # Turn relay off (turn lamp off)
    GPIO.output(23, GPIO.LOW)
    time.sleep(5)
```
Explanation:
This code uses the RPi.GPIO library to access the GPIO pins on the Raspberry Pi 4 board. It sets up pin 23 as an output and then enters an infinite loop, toggling the relay on and off every 5 seconds, which controls the home appliance connected to the relay.
