Raspberry Pi 3 Kit DocumentationOverviewThe Raspberry Pi 3 Kit is a single-board computer and a popular choice for IoT projects. It features a quad-core Cortex-A53 CPU, 1GB of RAM, and on-board Wi-Fi, Bluetooth, and HDMI capabilities. This kit provides a comprehensive platform for building IoT applications, prototyping, and learning.Components IncludedRaspberry Pi 3 motherboard
Power adapter
MicroSD card
HDMI cable
USB cable
Wi-Fi and Bluetooth antennasProgramming LanguagesThe Raspberry Pi 3 Kit supports various programming languages, including Python, Java, C++, and more. For this documentation, we will focus on Python examples.Example 1: Blinking LED using GPIOIn this example, we will use the Raspberry Pi's GPIO pins to blink an LED.Hardware Requirements1x LED
1x 220 resistor
1x Breadboard
Jumper wiresSoftware RequirementsRaspbian OS (latest version)
Python 3.x installed on the Raspberry PiCode
```python
import RPi.GPIO as GPIO
import time# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Define the LED pin
LED_PIN = 17# Set the LED pin as an output
GPIO.setup(LED_PIN, GPIO.OUT)try:
while True:
# Turn the LED on
GPIO.output(LED_PIN, GPIO.HIGH)
time.sleep(1)
# Turn the LED off
GPIO.output(LED_PIN, GPIO.LOW)
time.sleep(1)
except KeyboardInterrupt:
# Clean up GPIO on exit
GPIO.cleanup()
```
Example 2: Wi-Fi Connectivity and HTTP RequestIn this example, we will use the Raspberry Pi's Wi-Fi capabilities to connect to a network and send an HTTP request.Hardware RequirementsNone (uses the on-board Wi-Fi module)Software RequirementsRaspbian OS (latest version)
Python 3.x installed on the Raspberry Pi
`requests` library installed on the Raspberry PiCode
```python
import requests# Set Wi-Fi credentials
WIFI_SSID = "your_wifi_ssid"
WIFI_PASSWORD = "your_wifi_password"# Connect to Wi-Fi
print("Connecting to Wi-Fi...")
import subprocess
subprocess.run(["sudo", "iwconfig", "wlan0", "essid", WIFI_SSID])
subprocess.run(["sudo", "iwconfig", "wlan0", "key", WIFI_PASSWORD])
print("Connected to Wi-Fi!")# Send an HTTP request
response = requests.get("https://www.example.com")
print("HTTP Response:", response.status_code)
```
Example 3: Temperature and Humidity Reading using DHT11In this example, we will use the Raspberry Pi's GPIO pins to read temperature and humidity data from a DHT11 sensor.Hardware Requirements1x DHT11 temperature and humidity sensor
1x Breadboard
Jumper wiresSoftware RequirementsRaspbian OS (latest version)
Python 3.x installed on the Raspberry Pi
`Adafruit_DHT` library installed on the Raspberry PiCode
```python
import Adafruit_DHT# Set up the DHT11 sensor
DHT_SENSOR = Adafruit_DHT.DHT11
DHT_PIN = 4# Read temperature and humidity data
humidity, temperature = Adafruit_DHT.read(DHT_SENSOR, DHT_PIN)print("Temperature: {:.1f}C".format(temperature))
print("Humidity: {:.1f}%".format(humidity))
```
These examples demonstrate the Raspberry Pi 3 Kit's capabilities in GPIO control, Wi-Fi connectivity, and sensor integration. With this kit, the possibilities for IoT projects are endless.
