And now that I've posted one normal message, i can include links. smiley

Actually robomaa is not the only webshop in finland supplying arduinos.

You should check out paeae technologies
Site also availible in english  smiley-wink

I'm having the same issue using ethershield+sd with arduino.
I tried the demo that came with webduino and toggled some outputs on and off. Only pin 9 gave me almost full 5 volts. Other pins that i tried only gave 0,2 or so volts.
I tried using USB-power and 9volt battery connected to 2,1mm jack with no luck.  smiley-sad

Yeah. You are right. That's why I used quotation marks  ;D
5  Forum 2005-2010 (read only) / Exhibition / "Hollywood style" timer & "detonator" on: November 19, 2010, 09:36:17 am
This is a learning project just to teach myself IF and WHILE functions and testing my newly obtained LCD screen.
Basicly this code makes arduino count down from 120 while printing value on screen and when timer reaches zero, detonatorPin goes high.
Code is buggy and crappy and all that, so i appreciate any comments and improvements!

Also sorry for my crappy english smiley

Can you include schematics?
