Hello, I need to connect 3 function buttons on my UDOO QUAD. Each of these must play a role: 1 opens VLC 2 press "play" 3 closes VLC I have no idea how to do it and the hardware I need. On the forum I have not found anything relevant. The system installed is Debian (boot from sata). Each button must be connected via a cable 15 meters long. Thank you all for the answers.
