• Creating a holographic clock using arduino
  Recently, I came across a video of an Arduino project called "Holographic clock"
  This device consists of reflecting matrices in a plexiglass plate.
  Having all the required equipment on hand, I get to work.
  I did not want to monopolize an Arduino for this project, but to connect it to the box already used to manage the addressable LEDs all around my workshop.
  I begin by soldering an old ADSL cable to the wires needed to power and control the matrices that I had repaired in
