First off, kudo's for the instructions in the 4bit playground page. If I had been paying attention to the datasheet I found for my display, I'd have got it working the first time smiley (For some reason the pin numbering is ass-backwards on my LCD). Still, I have a small question. For now, the random fruit example works perfectly. Single line, scrolling, all the bits. But, if I enable the 2nd line and the commented out 'score' bit the display stays empty. No noise, no nothing. Backlight comes on, but no character appear. Am I missing something, or have my earlier attempts killed just the second line? The display is a pc1602f, which should be hd44780 compatible.

(excuse me for lifting this old thread from the depths of oblivion)

Ladyada, I'd like to thank you for writing the tutorial. I bought an Arduino mainly on the basis of seeing your tutorials. They are really well written, and easy to follow for someone who has just minor knowledge of electronics. Kudo's, therefore. And, I eagerly await the next lesson smiley-wink
