Hallo Zusammen
Ich möchte mir folgendes Oszi bauen: Arduino Oscilloscope
Kann ich dieses Oszi mit einem Uno realisieren wohl eher nicht hier nochmals der Sketch:

Leider musste ich den Sketch einkürzen ( die Zeilen am Schluss) da sonst die zulässige Zeichenlänge überschritten wird.
Eventuell kann jemand ja was aus den Code oder dem Plan rauslesen.
