Hallo zusammen,
ich habe mir ein kleines POV gebaut. Leider habe ich etwas Probleme bei der Erweiterung des Codes von Michael Zöllner.
Das Problem ist folgendes:
Ich habe zusätzlich einen Tiltsensor verbaut. Leider bekomme ich es nicht hin, dass die Buchstaben immer in eine Richtung angezeigt werden. Je nach dem, wo man beim "Schütteln" ist, werden die Buchstaben spiegelverkehrt angezeigt. Vielleicht könnt ihr mir ja helfen.
Danke euch.

connect anodes (+) of 5 leds to digital ports of the arduino board
and put 20-50 ohm resistors from the cathode (-) to ground.
the letters are lookup tables consisting arrays width the dot status in y rows.
