Category: 비트

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.

    Claire T. ★★★★★

    My son claps once and the whole circuit lights up, which is exactly the reaction I was hoping for. The threshold dial takes a little fiddling to ignore background noise, but once it's set it triggers reliably.

    Sophia Y. ★★★★★

    Wired this between a power Bit and a bright LED, and now my kid just yells at the circuit to switch the light on. The threshold dial takes a little fiddling to find the right room noise level, but once it's set it reacts fast.
