This interactive electronic birthday card allows the recipient to interact with the card in a unique way. The card appears to have flickering candles on top of a birthday cake by using individually PWMed LED's. Using microphones, I have characterized the noise signature of someone blowing out the candles. When this signature is recognized, the LED's will start to go out depending on their location to the microphone. This gives the user the sensation of blowing out the candles. Once all of the candles have been blown out, the card will sing you happy birthday by using a piezo-electric buzzer.
