MK103 - Light-sound gadget

Description

Kit is a simple sound switch. Four LED diodes with increased light intensity were used as signaling of the reaction. The device has its own microphone. His sensitivity and hence the sensitivity to the surrounding sounds is regulated in a smooth way - with a potentiometer.

The set will work great as an indicator of the presence of sound, for example, phone ringing or door signal.
The system is perfect for experiments, it can be easily expanded and supplemented, for example, with a relay.

The device is especially recommended for people who want to wirelessly control other devices as an additional ringing signaling device
