-To find your Pi on the net one can use this command:+

 +To find your Pi on the local net one can scan it with this comand:
    $ sudo arp-scan -l    $ sudo arp-scan -l
-Log in with ssh pi@ 192.168.???.????+Log in with: 
 + $ ssh pi@ 192.168.???.???? 
 +on the Pi update and upgrade: 
 +  $ sudo apt-get update 
 +  $ sudo apt-get upgrade 
 +Install the omxplayer: 
 +  $ sudo apt-get install omxplayer 
 + 
 +=== Autostart === 
 + 
 +To create the autostart open: 
 +  $ sudo nano /etc/rc.local 
 + 
 +and write before "exit 0" the following: 
 +  printf "  \n" 
 +  printf "    =============================================\n" 
 +  printf "    =             MY VIDEO LOOP                 =\n" 
 +  printf "    =                                           =\n" 
 +  printf "    =          wolfgang spahn 01-2021           =\n" 
 +  printf "    =         http://dernulleffekt.de           =\n" 
 +  printf "    =============================================\n" 
 +  printf " \n" 
 + 
 +If one wants to run an additional program these line should be added: 
 +  # start LEDs blinking 
 +  printf "start to blink an LED on GPIO 27\n" 
 +  /home/pi/python/blink_02.py & 
 +e.g.: 
 +   $ wget http://www.dernulleffekt.de/programme/blink_02.py.tar 
 +   $ tar xf blink_02.py.tar 
 +   $ sudo chown root:root blink_02.py 
 +   $ sudo chmod 755 blink_02.py 
 + 
 +And to start the omxplayer add that: 
 +  # start the omxplayer 
 +  printf "start the video loop\n" 
 +  omxplayer /home/pi/video/myvideo.mp4 & 
 + 
 +To run the omxplayer in the background one has to add the "&" at the end of the line.\\ 
 + 
 +Copy the video to /home/pi/video. It should be has to be an mp4 (H264) format.\\

 +---- 
 +==== all in one USB cable ==== 
 + 
 +To power and simultaneously connect an USB hub to the Raspberry Pi Zero with just a single USB cable one needs an [[https://en.wikipedia.org/wiki/USB_On-The-Go|USB-OTG]] cable.\\ 
 + 
 + 
 +An other possibility would be this [[raspberry:pi_zero_usb-otg|Pi Zero USB-OTG Hack]].\\

 +===== Read Only =====
 +For preventing any data loss while turning off the Pi one has to change the SD card to read only: [[raspberry:read_only|Read-Only SD Card]]
