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. Check out makezine.com for all the details of the build.
