I have found that if you were to want to be completely evil you could make a stack of these wheels and place them in the treasure hunt. In the characters on the wheel place a word or a series of symbols that would identify that one wheel different to the others. The codes could change at every clue. This is just the basic hardware of the thing. Use your artistry and make it spectacular! If you a make it, please share as I am actively making a treasure hunt and could use all the ideas that I can get on this front.

I agree for the standard scrawl to remind myself of the cat or the groceries this is a bit cumbersome. But for that special touch it's a tool in my bag to make the wife go awww. That and I use them for my treasure hunts to print clues on and stick to things.
or more specifically lcd.print(f("blah blah"));
Most of the Serial.prints I commented out when I was getting toward the end of the build. Would that work for the lcd.print("blah blah"); ?
