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.
# Small and cheap shield for Arduino: #
This is a conversion of my project C_meter_ATtiny2313
from Attiny2313 to shield for Arduino uno R3. All describe about a techique is actual.
Build is in progress.

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...
This is a project which is reproduced from arduino.cc Arduino Mega 2560. Using EasyEDA to re-layout the PCB.

BTW, This project is **not imported** from an Eagle, I have done some modification.
