The Arduino Birthday Cake is No Lie
Making someone a birthday cake is very thoughtful, but not if they are watching their weight. [MrFox] found a way around that: an Arduino-powered birthday cake. Even if you don’t mind the calories, an Arduino cake is a novelty and sure to be a hit with a hacker who’s another year older.
The cake uses a UTFT LCD shield which eats up a lot of pins and memory, so the project uses an Arduino Mega. A speaker plays the happy birthday song (which may even be legal now) while a microphone detects the birthday boy or girl blowing out the virtual candles.
We’ve seen similar cakes with a fixed number of LED “candles” before, but the LCD screen makes this a cake of a different color. If you want, you could look into something that is actually edible. On the other hand, we’re kind of partial to the Jolly Wrencher with red eyes and fireworks, ourselves.
The video shows the birthday cake in action. Given the screen, we were surprised that nothing popped out. Not a life-changing project, but still fun for your next hacker party, even if you have a real cake as a backup.
