Then, you can start it immediately by running:
$ su -c 'systemctl start lightsequences.service'
To make this service start on each boot, run:
$ su -c 'systemctl enable lightsequences.service'
From here, you have many options to expand and customize your light display. Having
Ethernet included means you could add a web-based interface to start and stop the
lights or to control them. Thanks to the audio-out jack, you can even use it as the sound
source.
You could combine this hack with
Hack #49
to send the sound through a radio broad-
cast. With serial input coming in, you could use a MIDI sequence to control both lights
and sound. With an attached camera, you could serve a picture of your changing dis-
play to the Web. And thanks to the Raspberry Pi, that's all readily available in one
package. Happy holidays!
