Raspberry pi python code examples github

I'll respond in English and provide Raspberry Pi Python code examples from GitHub.

The Raspberry Pi is a popular single-board computer that has gained widespread adoption due to its affordability, portability, and ease of use. Python is one of the most widely used programming languages on the Raspberry Pi, thanks to its simplicity and versatility. Here are some interesting Raspberry Pi Python projects and their corresponding code examples from GitHub:

from picamera import PiCamera
import time
camera = PiCamera()
camera.resolution = (640, 480)
camera.framerate = 30
camera.start_preview()
time.sleep(2)
while True:
camera.capture('image.jpg')
print("Captured!")

import RPi.GPIO as GPIO
from datetime import datetime
GPIO.setmode(GPIO.BCM)
Initialize pins for sensors
temp_pin = 17
hum_pin = 23
press_pin = 24
try:
while True:
Read sensor data
temp_value = GPIO.input(temp_pin)
hum_value = GPIO.input(hum_pin)
press_value = GPIO.input(press_pin)
Print the values
print(f"Temperature: {temp_value} C")
print(f"Humidity: {hum_value} %")
print(f"Pressure: {press_value} hPa")
time.sleep(1)
except KeyboardInterrupt:
GPIO.cleanup()

import RPi.GPIO as GPIO
from flask import Flask, render_template
app = Flask(name)
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)  # Lamp pin
GPIO.setup(23, GPIO.IN)   # Motion sensor pin
@app.route('/')
def index():
return render_template('index.html')
if name == 'main':
app.run(debug=True)

import speech_recognition as sr
r = sr.Recognizer()
mic = sr.Microphone()
try:
with mic as source:
audio = r.listen(source, timeout=3)
text = r.recognize_google(audio)
if "hello" in text:
print("Hello!")
elif "goodbye" in text:
print("Goodbye!")
else:
print(f"You said: {text}")
except sr.UnknownValueError:
print("Could not understand")

These code examples demonstrate the versatility of Python on the Raspberry Pi and showcase some interesting projects that can be created using this powerful combination.

Raspberry pi python code examples for beginners

I'll respond with English-only code examples for Raspberry Pi and Python programming for beginners. Here are some examples to get you started:

Hello World

print("Hello, World!")

This is a classic "Hello, World!" program that prints the message to the screen.

Getting Started with GPIO

The GPIO (General Purpose Input/Output) pins on your Raspberry Pi allow you to interact with physical devices. Here's an example of how to set up a simple LED circuit:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
LED_PIN = 17  # pin number for the LED
GPIO.setup(LED_PIN, GPIO.OUT)
GPIO.output(LED_PIN, True)  # turn on the LED

Reading from a Sensor

The Raspberry Pi has various sensors built-in or available through add-on boards. Here's an example of how to read from a temperature sensor:

import Adafruit_DHT as dht
dht_sensor_pin = 4  # pin number for the DHT11 temperature and humidity sensor
temperature, humidity = dht.read_retry(dht.DHT11, dht_sensor_pin)
print(f"Temperature: {temperature}C")
print(f"Humidity: {humidity}%")

Controlling a Motor

The Raspberry Pi can control motors through various interfaces like the PWM (Pulse Width Modulation) module. Here's an example of how to control a DC motor:

import RPi.GPIO as GPIO
motor_pin = 18  # pin number for the motor
GPIO.setup(motor_pin, GPIO.OUT)
pwm_value = 50  # set the pulse width modulation value (0-100%)
GPIO.output(motor_pin, pwm_value)

Basic Networking

The Raspberry Pi can connect to the internet and send data. Here's an example of how to send a simple HTTP request:

import requests
url = "http://example.com/api/temperature"
data = {"temperature": 22.5}
response = requests.post(url, json=data)
print(response.status_code)  # print the response status code

Working with Files

The Raspberry Pi can read and write files to its file system. Here's an example of how to write a simple text file:

import os
file_name = "example.txt"
with open(file_name, "w") as f:
f.write("Hello, World!")
print(f"File {file_name} created successfully!")

These examples demonstrate basic programming concepts and interact with the Raspberry Pi's GPIO pins, sensors, and network capabilities. As you continue to learn and experiment, you'll be able to create more complex projects that combine these fundamentals.
