Just an obvious suggestion - you have got the baud rate in Serial Monitor set to 9600 haven't you?

I've only had a quick skim through your code but I can't see how you are connecting to the shield? And what shield, and where did you get the the GSM library from?

Back on topic, you can buy dummy batteries for this purpose. Look like (or at least similar to) a battery but it's just a metal strip from one end to the other!

I've just picked a listing at random:

Your photo is over 2Meg in size so I won't be downloading it but...

have you read the 'Warning...' sticky at the top of the forum page? I have to admit that I haven't read it all but it looks like your display is similar to the ones discussed on there?

And I have to agree with what raschemmel says - they aren't worth the effort if they suddenly stop working for no obvious reason. Put it in a drawer until you can have a play around with it.
95  Using Arduino / Project Guidance / Re: Need help with ARDUINO timing accuracy on: March 18, 2014, 04:09:13 pm
The Uno at least uses a 'ceramic resonator' as opposed to a crystal. I went to my favourite electronics supplier and looked up the spec for a similar part:

Frequency tolerance   ±0.5%
Frequency stability   ±0.3%
Ageing   ±0.3% over 10 years

You are more likely to get help if you give your post a suitable title - did you read the sticky at the top of the forums?

What do you mean by 'accurately'? All the Arduinos are dependent on the timing source for their accuracy, so there will (nearly) always be some degree of inaccuracy.
97  Using Arduino / Project Guidance / Re: sms notification . on: March 15, 2014, 07:27:38 am
Which shield have you got? What happened when you tried the program? And which program - there's quite a few on that page?

I've used iTead a few times, no complaints at all. The only reason I currently use Elecrow is that they do coloured boards for no extra charge!
99  Products / Arduino GSM Shield / Re: GSM and Serial Monitor on: March 14, 2014, 08:47:18 am
1) I would upload the code without the shield attached.
2) You don't need to use sscom32, the Serial Monitor will do what you need.

Based on what you have said above, at the top of your sketch add the lines:

#include <SoftwareSerial.h>

SoftwareSerial GSM(3, 2);

And then change every instance of 'Serial.' to 'GSM.'

Then upload and try it.

Which Arduino are you using? You would normally use SoftwareSerial to talk to the GSM board, in this case using D2 & D3, and leave D0 & D1 so you can communicate with  the Arduino using the Serial Monitor. And don't forget the note about using the correct power supply!

Hope you have fun with it and if you get stuck you can always ask on there forum!
102  Using Arduino / Project Guidance / Re: HELP with an Arduino Digital Camera on: March 11, 2014, 05:55:02 pm
Having read the product reviews it doesn't look good I'm afraid to say.

The basic Arduino doesn't have the processing power to do much, if anything, with images. The cameras usually have the capability to write to SD card directly, and the Arduino does peripheral things, such as deciding when to take a picture, pointing the camera in the right direction, etc.
103  Using Arduino / Project Guidance / Re: HELP with an Arduino Digital Camera on: March 11, 2014, 05:33:24 pm
Did you read the sticky at the top of the page about using the forum?

Links? Code?
104  Using Arduino / Project Guidance / Re: Help with first project. Code sketch on: March 11, 2014, 04:24:40 pm
Is the fact that you have eight sensors and the bit pattern is eight characters long any way connected?
105  General Category / General Discussion / Re: Arduino Tinkerkit on: March 11, 2014, 04:08:47 pm
As far as I can tell it is the same kit as this one:

http://store.arduino.cc/index.php?main_page=product_info&cPath=2_23&products_id=133

But blimey, that seems expensive!

Again as far as I can tell you will also need an Arduino Uno to go with the kit.
