Check out Angela Yuan’s Etch-A-Scetch Clock. An Arduino powers a few stepper motors that clear the screen once a minute and then draw the current time.

It looks like there is a laptop that is sending commands, presumably time updates, to the Arduino via processing. Her site is a little scant on details, but there are a few useful links that will give you a good start if you’d like to build your own.

  1. Very nice, using the output to Firebug Console.

    But…from a practical angle,
    what’s the code to display the 3 query results
    in the web page itself,
    not in the Firebug Console?

    (3 results displayed in the page
    containing the 2 tables, “users” and “photos”…).
