How-to Tuesday: Valentines LED display

http://blog.makezine.com/archive/2009/01/howto_tuesday_valentines_led_display.html

This week I am going to be making the Open Heart kit from the Maker Shed. The Open Heart kit uses a technique called Charliplexing for lighting up the LEDs. Why? Well, Charlieplexing allows you to control each LED’s state individually. All you need to do is create a simple program and upload it to the Arduino and you have a really cool animated LED display.
