DIY LED Heart

We live in the information age. Your phone knows where you like to eat, computer programs know what movies you like better than you do, and going to a party can mean going in this life, or a Second Life. So why is your message of love still stuck in the 16th century? These days it takes more than a sonnet to melt a girl’s heart. This video tutorial shows step-by-step how to make a Valentine’s Day card for the digital age. The NerdKits team shows how to make an LED Heart Valentine’s card powered by a microcontroller. The heart features an LCD screen for a personalized message, and 20 LEDs around the perimeter that can be programmed to show any pattern. The code provided contains a “twinkle” function that randomizes the process to provide a true star-like twinkle.
