Step-by-step Raspberry Pi setup for your first LED or sensor project.

• Gather Raspberry Pi and accessories

  Include power supply, microSD (16GB+), case, HDMI/adapter, keyboard, mouse, and jumper wires.

• Download Raspberry Pi Imager and OS image

  Get Raspberry Pi Imager and the recommended Raspberry Pi OS from raspberrypi.org.

• Flash OS to microSD using Raspberry Pi Imager

  Select the OS and the correct microSD device; verify before writing.

• Enable SSH and configure Wi‑Fi in Imager advanced options

  Open advanced options (gear icon) to pre-enable SSH, set Wi‑Fi SSID/password and timezone.

• Set hostname and locale in Imager advanced options

  Choose an identifiable hostname and correct locale/keyboard layout.

• Create 'ssh' file and wpa_supplicant.conf on the boot partition

  Add an empty file named 'ssh' and a properly formatted wpa_supplicant.conf for headless Wi‑Fi.

• Insert microSD, connect peripherals or power for headless boot, and start the Pi

  Attach power last; watch LED/boot messages on HDMI or wait for network availability.

• Find the Pi's IP address and connect via SSH

  Check router admin, use nmap, or a network scanner app to locate the Pi and SSH to it.

• Change the default password and secure user accounts

  Run passwd for the pi user, create a new user if desired, and remove or disable defaults.

• Update OS packages and firmware

  Run sudo apt update && sudo apt full-upgrade -y, then reboot if required.

• Install essential tools (git, python3-pip, gpiozero)

  Install packages useful for projects: git, build-essential, python3-pip, gpiozero.

• Enable GPIO interfaces (I2C, SPI) and camera via raspi-config

  Run sudo raspi-config → Interface Options to enable I2C, SPI, and other needed interfaces.

• Wire and test a simple LED project using gpiozero

  Connect an LED with a 330Ω resistor to a GPIO pin and ground, then run a blink script.

• Connect a basic sensor (DHT11/DHT22) and read values with Python

  Wire sensor to power, data pin, and ground; install required libraries and run a sample script.

• Create a backup image of the configured SD card

  Use dd or an image tool to snapshot the working SD card for easy recovery.
