Check out this handy Arduino Voc Trainer project from Thomas Lenarz in the Adafruit Forums!
Arduino Vocabulary-Trainer 0.2
This is the second version of my little Arduino vocabulary-trainer.
Now, it is able to display some french accents and “cedile” via the self definable characters of the LCD. Words being longer than 16 characters are scrolled horizontally.
It tests the vocabulary in both directions (French German, German French) in random order.
