LED (any color)
1 k resistor
Breadboard
Jumper wiresSoftware RequirementsRaspbian OS (latest version)
Python 3.xCode
```python
import RPi.GPIO as GPIO
import time# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Set up GPIO 17 as an output
GPIO.setup(17, GPIO.OUT)try:
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)except KeyboardInterrupt:
# Clean up GPIO on exit
GPIO.cleanup()
```
### Example 2: Web Server using Python and FlaskThis example demonstrates how to create a simple web server using Python and Flask on the Raspberry Pi Zero W.Hardware RequirementsRaspberry Pi Zero W board
Internet connection (Wi-Fi or Ethernet)Software RequirementsRaspbian OS (latest version)
Python 3.x
Flask (install using `pip install flask`)Code
```python
from flask import Flask, render_templateapp = Flask(__name__)@app.route("/")
def index():
return "Hello, World!"if __name__ == "__main__":
app.run(host="0.0.0.0", port=80)
```
Run the script using `python app.py` and access the web server using a web browser at `http://<Raspberry Pi Zero W's IP address>`.### Example 3: Wi-Fi Connectivity using PythonThis example demonstrates how to connect to a Wi-Fi network using Python on the Raspberry Pi Zero W.Hardware RequirementsRaspberry Pi Zero W board
Wi-Fi routerSoftware RequirementsRaspbian OS (latest version)
Python 3.xCode
```python
import network# Set up Wi-Fi interface
wlan = network.WLAN(network.WLAN STA_IF)# Set Wi-Fi credentials
wlan.connect("your_wifi_ssid", "your_wifi_password")# Wait for connection
while not wlan.isconnected():
passprint("Connected to Wi-Fi!")
print("IP Address:", wlan.ifconfig()[0])
```
Replace `"your_wifi_ssid"` and `"your_wifi_password"` with your actual Wi-Fi credentials.These examples demonstrate the versatility of the Raspberry Pi Zero W and its ability to be used in various IoT projects, from simple GPIO control to web development and Wi-Fi connectivity.
