 One of your 'if (buttonState == HIGH) {'   has the curly brackets after it, the others don't.   I think you meant to have them on each section.

You would be much better deleting all but one button and one led, get that working, then introduce subsequent items line by line without breaking the original function.  ('step by step' as previously said).

You don't need "== HIGH",  'if (buttonState)  is sufficient.  Its zero or something.

Can you give the 4A device its own pair of wires from the battery?

Thanks for that, and sorry for the delay getting back. I've upgraded to 1.5 and started looking at platform.txt.

Coils in stepper motors have the current flowing either way at differnt times. Usually done by switching each end between +v and 0v. Usually with dedicated  chip but you could do it straight fom these outputs.

Hello,

I'm new to the Arduino and the forum.  I went looking for a command-line build for Arduino programs.  Found this http://playground.arduino.cc//Code/WindowsCommandLine, and tried abuild.bat.  It doesn't work for me, and it says 'report any problems to http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1168127321;start=all.  So I went there, but it is 'read-only' - because it's old? (or I'm new?)  Is it still supported?

I just want to build the software and load the Arduino from a command line.  I've tried some of the makefiles, but not managed to get one to work all the way through.

Any help appreciated.

Richard.
