Log in as user: pi with password: raspberry (if you use a wrong keyboard layout, the y may be at the z position, but you don't see it because the password is not visible). It corresponds to the common way to use a Linux computer. This is the most direct working environment given that you owe a HDMI or DVI monitor and you are familiar with Linux. You may work in the Linux command shell or start the Raspian desktop. To access the Raspi Linux system, a screen, keyboard and mouse can be plugged directly into the RPi ports.

Autostartup displaying IP address (playing/showing last three numbers as Morse code on GPIO pin 22).The main features of our RaspiBrick firmware are: Consult the RaspiBrick installation site for more information. Moreover you can download our 8GB SD-card image from here and you are ready to go. We provide some useful addons to the NOOBs installation as GitHub distribution. Furthermore to facilitate debugging, all output to stdout and stderr (print and error messages) are automatically reported back to the development system and shown in a terminal window without changing any line of code. But in contrast to the Arduino, it is not the machine program, but the source script that is downloaded to the target, where the Python interpreter executes it. The development cycle then resembles to the procedure commonly used with other microprocessor systems like the Arduino, where programs are written/compiled on a " host" and downloaded to the " target" for execution. This shields you from the details of the Linux operating system. But finally we recommend " remote development" with an IDE that runs locally on your notebook/desktop. In this section we present current procedures for programming Python on the Raspberry Pi. Frustrations with the IDE and the lack of appropriate error messages may spoil your teaching efforts and break down interest and motivation for programming. Whatever you decide to use, do not underestimate the importance of a simple and stable development environment for beginners.

We recommend P圜harm (by JetBrains) for the professional programmer and TigerJython (by Tobias Kohn) and Geany for occasional users, kids and students. There are several attempts to overcome this deficiency, but modern Python IDEs that are simple to use, but hides the ugly Python shell are still rare.
In modern times where people are accustomed to sophisticated graphical user interfaces, this way of working is outdated. Then the Python interpreter is started that displays an old-style (black) terminal window and the script is loaded and executed using old-fashioned command lines. Because Python is an interpreted language, the development cycle is simple: Any text editor can be used to write the source program (often call a Python script). But the number and the quality of development environments for Python is still poor. Countless programs and library modules are available for all kind of activities using the GPIO interface. The main programming language for the Raspberry Pi is Python.
