Floating Message
Published in issue 391, July/August 2009
This project lets you display a message floating in the air using just seven LEDs, a microcontroller, and the movement of your arm. The LEDs flash at a frequency of the order of 200 Hz, and so all you have to do is move the circuit around to see the message appear as if it were floating in mid air.
