The Arduino platform has become quite popular with people just starting out with electronics. It is an open-source hardware design, based on microcontroller board designs and provide sets of digital and analog I/O pins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading pro...

BTW, This project is **not** imported from an Eagle, I have done some modification.
Sensor for sound detection, the module has two outputs:
AO, analog output, real-time output voltage signal of the microphone
DO, when the sound intensity reaches a certain threshold, the output high and low signal
The threshold-sensitivity can be adjusted via potentiometer on the sensor.

This is the adaptation for Arduino UNO R3 of **Adrzej Janeczek project** “AVT-2813” - Multimeter addition for L measurement.
