compumike writes "If you have a significant other to impress this Valentine's Day, consider putting your programming skills to use. This video tutorial shows how to build an LED Heart Valentine's card, powered by a microcontroller running C code, with a neat randomized 'twinkling' effect in an interrupt handler. Think about it: how many ladies can say that their Valentine's card runs at 14 MHz?"
