Heads Up! is a speaker box hack – hiding a foam disc gun with a speaker inside, linked to a Wifi connected Huzzah arduino board. The board is triggered through the IFTTT service using a Twitter applet sending data when the hashtag #headsupPOD is tweeted. When data is sent to the board, the servo motor is triggered to pull the gun trigger to fire the foam discs. After just the right delay, the audio board is triggered to activate an audio file shouting “Heads up!”.
