We try to help you with 'your' sketches.

Always show us your ‘current’ compete sketch.
Use CTRL T to format the sketch.
Please use code tags.
Use the </> icon in the posting menu.

[code] Paste sketch here. [/code]

Show us a good schematic of your circuit.
Show us a good image of your wiring.

What things have you done using the Arduino so far?

I'm assuming that everyone uses the same software, so why can't I just attach a copy of the program file? You could view it and edit it and send it back to me with comments both in the replies and in the comments in the program.
