Shortly after reaching the 50 project milestone, today the nxtprograms.com web site reached another milestone by turning one year old! So here is a one-candle birthday cake project to celebrate.
The flame on the candle of the cake will "flicker" while the NXT plays the "Happy Birthday" song ,and when the song finishes, you can make a wish and blow out the candle. The sound sensor will detect the blowing, and then the flame will disappear!
Here is a video of the cake in action:
