A small and affordable computer that you can use to learn programming

• Micro Sd card will be needed with capacity >= 8 Gb (for installation without GUI 4Gb card can be used)

• Download latest raspbian os (debian based os for raspberry devices)

• Examine these instructions windows setup, linux setup, headless-setup, remote vnc, wifi.

• For GPIO interface communication wiring Pi should be installed This will allow you to communicate with GPIO pins directly via board CLI.

  For example:

  # prints pin diagram appropriate to your Pi
  gpio readall    

• install rpi.gpio module to communicate with GPIO pins from Python scripts

  sudo apt-get update
  sudo apt-get -y install python-rpi.gpio
  
  # sudo apt-get -y install python3-rpi.gpio  # for Python3

Protect your device and to avoid situations when it can be used without your permission.
