What’s better than birthday candles? LED animations of course! In this video we’ll tackle the age old question: can you embed LEDs into a birthday cake? Using flexible LED matrixes and an Arduino, Natasha explores how to incorporate the matrixes into a cake and drapes fondant icing over them to diffuse the light. It’s an exciting use case for LEDs and a spectacular birthday cake!
