littleBits Sound Trigger
This product is no longer available.
Use this Bit to control your circuits with sound! The sound trigger listens to the noise level in your room and sends an ON signal when it gets over a certain level. Try it with a Bit that lights up to create a circuit that responds to the snap of your fingers.
The sound trigger has a microphone that measures how much noise is around it. When the noise gets to a certain level the sound trigger will let the signal from the previous Bits through for 3 seconds. Use the adjustment dial to set what noise level youd like the Bit to be triggered at.
