Four high-intensity LEDs light up and react simultaneously to every sound. Use for different, fun, and practical applications like a sound indicator or simple sound-to-light unit for music. The unit can also be used to indicate when the doorbell or the telephone is ringing, which is particularly useful for the hearing-impaired. The sensitivity is adjustable with the potentiometer, and it has a built-in microphone.
Requires: 8-15VDC power supply or 9VDC battery, not included. We recommend Jameco P/N: (198731)
