It provides an I2C Bus which means that it can be connected to your Arduino or similar microcontroller with only two wires. I could’ve come up with a thousands things to do with this display: using it for showing notifications, as an RSS scroller or as a hardware dashboard with temperatures and statistics....
I recently purchased a very simple, Hitachi HD44780 compatible LCD screen for an Arduino project. It’s a 20x4 I2C display, which apparently is constructed as a combination of 2 two-line display controllers. This wouldn’t really matter except for the fact that when printing strings longer than a single line, they are displayed in a 1324 matter. So if you set your cursor on the first line and print a string 80 characters long, things get weird....

This is how it’s described on their website: Amblone stands for Ambilight Clone, and it is an open source ‘Do It Yourself’ solution for imitating Philips Ambient Lighting Technology. It projects light on the wall behind your TV or monitor in the colours that are currently on the screen....
