littleBits Sound Trigger

SKU: LBH811 Brand: LittleBits

The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers.

Use this Bit to control your circuits with sound. It's a great way to make your inventions hands-free! The sound trigger has a microphone that measures how much noise is around it. When the noise goes above a certain level, the sound trigger will send out an on or 5 volt signal to the following Bits in the circuit. Use the adjustment slider to set the sensitivity (how much noise is needed to trigger your Bit).

This i20 sound trigger bit uses a microphone to detect audio. The audio signal from the microphone is first amplified to increase the sensitivity of the module. Next, the signal is passed through a circuit that behaves similarly to our timeout module: when the peaks from the microphone are higher than the detection threshold, the output is set high. Once the microphone signal drops below the threshold, the output returns low again.
