This checklist guides beginners through setting up a Raspberry Pi for a first hardware project. It covers flashing the OS, configuring headless SSH/Wi‑Fi, securing and updating the system, enabling GPIO, and completing simple LED and sensor projects.

  1. Gather Raspberry Pi and accessories — Include power supply, microSD (16GB+), case, HDMI/adapter, keyboard, mouse, and jumper wires.
  2. Download Raspberry Pi Imager and OS image — Get Raspberry Pi Imager and the recommended Raspberry Pi OS from raspberrypi.org.
  3. Flash OS to microSD using Raspberry Pi Imager — Select the OS and the correct microSD device; verify before writing.
  4. 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.
  5. Set hostname and locale in Imager advanced options — Choose an identifiable hostname and correct locale/keyboard layout.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. Update OS packages and firmware — Run sudo apt update && sudo apt full-upgrade -y, then reboot if required.
  11. Install essential tools (git, python3-pip, gpiozero) — Install packages useful for projects: git, build-essential, python3-pip, gpiozero.
  12. Enable GPIO interfaces (I2C, SPI) and camera via raspi-config — Run sudo raspi-config → Interface Options to enable I2C, SPI, and other needed interfaces.
  13. 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.
  14. 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.
  15. Create a backup image of the configured SD card — Use dd or an image tool to snapshot the working SD card for easy recovery.
