Some friends asked my wife to do a birthday cake for a girl of eight years. With her age she is crazy about princesses.
Well, what came to mind was that despite having done many projects with Arduino i had never applied electronics in a cake. So we decided to join forces and add some light (RGB LED) and movement (DC motor controlled with an L298) to the cake.
