Thanks Amedeo for the support, nice article! ;)
In this tutorial a demo project will be explained, communication is established between PHP and Arduino using a simple intermediate C program which runs as a Linux daemon. The concept used here is Unix local Sockets, a fast and effective way to perform IPC (or Inter-Process Communication) on ...

This might be trivial questions
I want to measure current and voltage from solar panel.
I ordered current / voltage sensor and until it arrives I want to play around.
Accuracy is not relevant now only the proportional changes 
I used tiny solar panel which does not give more than 5V
I connect the solar panel to ground and A0 read the analog pin and display the reading 
val=analogRead(solarpin);
val=val*(5.0/1024.0);
That is what i was looking for as it changes according to the light, on total dark the reading is 0, on bright sun around 2.5

Now for current, all I have now is the one in the pic
Will it be sufficient to connect the plus from solar to green plus on this sensor and the other end to A0
And this sensor 
vcc-vcc
ground - ground
out - A1
And read A1 as I did before?
Do I need something on that circuit to consume the current? Led?

and BTW the below link is the sensor  I bought and the chip they specify
In all similar sensors I saw the order of the pins as G O V and on mine it's G V S.

Yesterday I moved my AVR library to it's own repo:
https://github.com/MightyPork/avr-lib It's MIT licensed, so use what you want from it.

It's a collection of useful header/c files for programming Arduino with C (not the C++ thing).

Recent additions: UART communication, and VT100 commands.
Other, older things: Pin aliasing, Debouncer, WS2812B, HD44780 etc.
avr-lib - Utilities for AVR programming in C, aimed at m328 / Arduino.

Oh, what a day. For me it was art friday and some art days will probably follow. My day started with Arduino bug #3028 and continued with the Olimex +OLIMEX  MOD-MP3-X, provided by Stephan +Watterott electronic  - a great little board that can be controlled by serial port and that has virtually no lag. In the afternoon I ran in a broken RF link transmitter.

Why? I am assisting Peter Bux http://einstweilen.de/ at building a heavily modified Maneko Neki (variable speed, two interrupts, the aforementioned board to provide sound output and motion detection - no wires please!). This piece of art can be seen beginning with Spinnerei Rundgang at May 1st, 2015 in Leipzig. All code will be GPLed and if other artists or hobbyists have questions on the code, just contact me or Peter.

To be continued.

I am looking for a board similar to the ODroid C-1, or RPi2 however it must have 2 or more gig ethernet ports.  I don't care about video or sound.  Just quad core (1ghz+), 1+ gig ram and 2 or more ethernet.  Similar price point to the ODroid C-1 or RPi2 would be great.  Has anyone seen such a device?

I don't think you're going to find it yet, at least not at the Odroid/ Raspberry Pi price point. One of the HummingBoard models is close in hardware, but was well over $100 last I checked.

This is a little controversial in this communit,y but this is the new Arduino Zero Pro from Arduino SRL. The hardware is the same as the Zero being released soon by Arduino LLC.

I view this board as a clone for now and since I own a lot of clones, I have no problem with it. I just wish all the trademarks would get sorted out to save confusion. I am team neither.

+James A. Langbridge The current IDE from Arduino.org doesn't support everything yet and lots or libraries won't have support for the chip yet. It took a long time for Due support on lots of libraries, which I is why I opted for a simple LED base demo. I look forward to the Arduino.cc version of the software.

ArduinoPins.h to convert Atmega328 pin numbers to Arduino pin numbers
I know a fair few people who started with original Arduinos and then experimented with breadboard Arduinos or Shrimpingit (https://plus.google.com/u/0/108771917679899034526/about) projects.

It is at this point that it becomes clear the numbering sequence for the pins is not the same for the ATmega328 and the Arduino IDE/board. For example Arduino Pin 13 is actually Pin 19 on the IC.

This meant while developing I had to keep a cross reference to hand to translate the pin numbers from the IC pins to the Arduino IDE pins.
Not too bad for simple project and not too bad if you get it right first time, but if there is some debugging or changes then the differences can cause much frustration.
To fix this I  created ArduinoPins.h so I could use easily understandable variables for the ATmega328 pins and have that converted to the Arduino IDE pin numbers without me having to worry about it.

Not a very technical fix but for me very effective.
I've been having fun with different Arduino compatible implementations including being part of a team that created an Arduino Shrimp based kit for the Brighton Maker Faire based on the details for The Shrimp. http://shrimping...

I solve this by just not going anywhere near Arduino and its bizarre fetish for renaming the pins. PB0, PB1, PB2,... ought to be enough for anybody

Hey guys, I'm working on a little project. I will connect an arduino to an mp3-Player with 4 Buttons. Now I want to controll these buttons with the arduino.

The buttons of the mp3 player toggle 2,5-3v and my arduino works with 5v.

How can I archieve to control these buttons? Which parts do I need?
