Choose the model based on performance and project needs.

Getting Started with Raspberry Pi

What You’ll Need:

Raspberry Pi board
MicroSD card (16GB+)
USB-C Power supply
HDMI cable + monitor
USB keyboard + mouse
Internet (Wi-Fi or Ethernet)

Installing Raspberry Pi OS

Use the official Raspberry Pi Imager:
raspberrypi.com/software

Steps:

Install Raspberry Pi Imager
Choose “Raspberry Pi OS (32-bit)”
💽 Select your SD card
Click “Write” to flash the OS
Insert SD card into Pi and boot

First Boot and Configuration

On first boot:

Set locale, language, and time
Connect to Wi-Fi
Change default password
Update software

You’ll reach the desktop environment of Raspberry Pi OS.

Using the Terminal and Commands

The terminal is your Raspberry Pi’s command center.

Basic Commands:

sudo apt update       # Update package list
sudo apt upgrade      # Upgrade installed packages
ls                    # List files
cd                    # Change directory
pwd                   # Show current directory

Use terminal for system management, file navigation, and package control.

🐍 Programming with Python

Python is the official language of Raspberry Pi projects.

Hello World:

print("Hello, Raspberry Pi!")

Run scripts using Thonny IDE or IDLE.

Accessing GPIO Pins:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)

Use Python to control LEDs, sensors, and actuators.

Connecting and Using GPIO Pins

GPIO enables hardware interaction:

Use Cases:

Blinking LEDs
