interaktiver Aldi LED Streifen

Eine einfache Bastelei mit Ultraschallentfernungsmessung und Ausgabe auf einem LCD- Display und dem LED- Streifen. Eine gepatchte Version der Adafruit NeoPixel Lib. Datei:Adafruit NeoPixel Aldi.zip Für das Nokia 5110 das Lib http://www.henningkarlsen.com/electronics/library.php?id=44 kann man natürlich auch weglassen. Und den Code Datei:AldiLEDs hc sr04 ultraschall.ino.zip .
