LED
1k resistor
Breadboard and jumper wiresSoftware Requirements:Raspberry Pi OS with Python 3 installedCode:
```python
import time
import RPi.GPIO as GPIO# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Set up the LED pin as an output
LED_PIN = 17
GPIO.setup(LED_PIN, GPIO.OUT)try:
while True:
# Blink the LED
GPIO.output(LED_PIN, GPIO.HIGH)
time.sleep(1)
GPIO.output(LED_PIN, GPIO.LOW)
time.sleep(1)
except KeyboardInterrupt:
# Clean up
GPIO.cleanup()
```
Run this code on the Raspberry Pi Zero 2W to blink the LED connected to pin 17.### Example 2: Reading temperature and humidity using a sensor (DHT11)This example demonstrates how to use the Raspberry Pi Zero 2W to read temperature and humidity data from a DHT11 sensor.Hardware Requirements:Raspberry Pi Zero 2W
DHT11 temperature and humidity sensor
Breadboard and jumper wiresSoftware Requirements:Raspberry Pi OS with Python 3 installed
`Adafruit_DHT` library installed (`sudo pip3 install Adafruit_DHT`)Code:
```python
import Adafruit_DHT# Set up the DHT11 sensor
DHT_PIN = 4
DHT_SENSOR = Adafruit_DHT.DHT11while True:
# Read temperature and humidity
humidity, temperature = Adafruit_DHT.read(DHT_SENSOR, DHT_PIN)if humidity is not None and temperature is not None:
print(f"Temperature: {temperature:.1f}C, Humidity: {humidity:.1f}%")
else:
print("Failed to read data from sensor")# Wait 1 second before taking the next reading
time.sleep(1)
```
Run this code on the Raspberry Pi Zero 2W to read temperature and humidity data from the DHT11 sensor connected to pin 4.These examples demonstrate the basics of using the Raspberry Pi Zero 2W with an aluminum heatsink and 20x2 header. With its compact size and GPIO capabilities, this board is ideal for a wide range of IoT projects.
