1. Change the name:
  $ sudo nano /etc/hostname
in "duino-pi"\\

2. Change the host file
  $ sudo nano /etc/hosts
in:
    127.0.0.1       localhost
    ::1             localhost ip6-localhost ip6-loopback
    fe00::0         ip6-localnet
    ff00::0         ip6-mcastprefix
    ff02::1         ip6-allnodes
    ff02::2         ip6-allrouters
                              
    127.0.1.1       duino-pi

5. Change the password
  $ passwd

The passwd command allows you to change your password, you will be prompted for your old password, then you new password twice.

4. Reboot:
  $ sudo reboot

----
==== Script ====
Install the Shutdown/Reset Button and the Blink Program as startup programs.

1. Make an folder
  $ mkdir /home/pi/paper-duino-pi
  $ cd /home/pi/paper-duino-pi

2. Download and unzip the shutdown script
  $ wget http://www.dernulleffekt.de/programme/shutdownbutton_02.py.tar
  $ tar xf shutdownbutton_02.py.tar
  
2. Download and unzip the blink script
  $ wget http://www.dernulleffekt.de/programme/blink_02.py.tar
  $ tar xf blink_02.py.tar
  
2. Change owner & rights
  $ sudo chown root:root shutdownbutton_02.py
  $ sudo chmod 755 shutdownbutton_02.py
  $ sudo chown root:root blink_02.py
  $ sudo chmod 755 blink_02.py
  
3. Create the autostart:
    $ sudo nano /etc/rc.local
write before exit 0:
   # run reset and shutdown script
   printf "start shutdown aund reset button on GPIO 22\n"
   /home/pi/paper-duino-pi/shutdownbutton_02.py &
   # start blinking
   printf "start blinking on GPIO 27\n"
   /home/pi/paper-duino-pi/blink_02.py &
   
To save and leave press:\\   
CTRL+O, Enter, CTRL+X\\

4. Reboot
  $ sudo reboot
\\

----
==== Arduino ====
Install the Arduino IDE and the Paper-Duino-Pi modifications.

1. Install the Arduino IDE, type in command line:
  $ sudo apt-get install arduino

2. For the modification of the GPIO Pin and the Avrdude, the easiest way is to download the setup for the AlaMode board:
  $ wget http://dernulleffekt.de/programme/paper-duino-pi-setup_02.tar.gz
<del>[[http://git.io/alamode-setup]]</del>\\
unpack it,
  $ sudo tar xf paper-duino-pi-setup.tar.gz
and run the setup.
  $ cd paper-duino-pi-setup
  $ sudo ./setup
That will install a new version of the avrdude and will also do some Linux modifications (one for the alamode board).

3. To modifier the Arduino IDE setup for the Paper-Duino-Pi you have to type in the terminal:
  $ sudo nano /usr/share/arduino/hardware/arduino/boards.txt
Change the name of the board:
     alamode.name=Paper-Duino-Pi
The baud rate should be set to 57600:
     alamode.upload.speed=57600
Than change the fuses from 0xde to:
     alamode.bootloader.high_fuses=0xda
and save it!\\

4. Reboot
  $ sudo reboot

After resetting the Raspberry Pi a new serial port: dev/ttyS0 and a new board: Paper-Duino-Pi will appear in your Arduino IDE. For uploading a program use the Paper-Duio-Pi board and the ttyS0 port.\\
