**Open Solar Energy Diverter**
This project have the aim to divert not comsumed electricity produced by photovoltaic panel to water heater to keep energy produced in the area of usage.
This project is base on idea from [http://energie-autrement.blogspot.com/p/plans-eolienne.html]...
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 Ethernet.Using EasyEDA to re-layout the PCB.
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 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.
