Beschreibung	Ein multifunktionaler LED-Controller zur Steuerung unterschiedlicher LED-Lichtquellen wurde in Zusammenarbeit mit iArt Basel entwickelt. Es ist ein open source Gerät basierend auf der Arduino Plattform. Durch den Einbau eines LED-Driver-Shields lassen sich direkt High Power LEDs bis 60V ansteuern.
