The specification states that Spoel vermogen = 0.36W, so I wouldn't expect them to draw 400mA.

Try measuring the current draw with a multimeter?

Go to this site and search for 'Send2Pachube'

According to the Schema the board already has the transistors, kick back diode, etc, built in.

What are you using to power the Relais bord?

You probably know this already, but CME ERROR: 3 = Operation not allowed.

There is a Nederland section in the International area if you would be more comfortable in there?

Go and find a copy of Ken Shirriff's IR library http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html and then use IRrecvDump (included with library) to decode the various signals. It's a fairly straightforward process if your receiver is compatible.

Load the version of SerialRelay from the web page in my sig link.

Once the modem has locked on to a signal, issue the command AT&F - please note that this restores the factory default settings.

Issue the command AT+CMGF=1 to put it into text mode.

Now issue the command AT+CNMI=2,2,0,0,0 which will send all sms / texts received to the Serial Monitor.

Now send a message to the device and it should repeat on the Serial Monitor. I have tried 26 characters and all appear.

Code:
+CMT: "+44xxxxxxxxxx","","14/04/06,19:26:40+04"
Abcdefghijklmnopqrstuvwxyz

Edit: Changed the reset code and added the AT+CMGF=1 line. It doesn't affect the functionality but the result wouldn't be as shown.

That code won't even compile.

You don't (appear to) delete the messages from the sim card so try putting it in a  phone and see what the look like on there?

Homework time is it? I must admit you seem to have done more research than the usual.

Try the search box in the top right hand corner - this question comes up quite frequently.

It's not an answer to your question as such, but check the link in my sig below for some example sketches that may help you.

Have you tried Google?

About 13,900 results for SIM900D + Arduino

Have you tried the forum search? Top right hand corner of the screen? There has been some discussion about it in the past.

Hang on to the 328, it may be 'walking wounded' - try it in the new board to see. But it is unlikely. I've had processors overheat to the extent that I have burnt myself touching them but they still function afterwards. But I mark them so I know that they are now dubious!
73  Using Arduino / Installation & Troubleshooting / Re: Accidentally put 12V into 5V output on Uno on: April 01, 2014, 04:08:12 pm
Try the loop back test (see Sticky at the top of the page) but assume the worst.
74  Using Arduino / Programming Questions / Re: GPS and LCD UNITE kinda :/ on: April 01, 2014, 02:59:50 pm
I'd start by looking for a string starting with $GPGGA as that is the one that contains the satellite fix flag. Then once you have that you can either use that string or $GPRMC string for your location.

To parse the string in a simple way to start with just look for 'n'  commas before the data you want.

He wouldn't see the blocks if the contrast wasn't set somewhere near where it should be.

With all respect Don, I have fully functioning displays that with the contrast set to the limit they display blocks and not characters. Granted it doesn't take too much adjustment to make the transition, but nonetheless it happens.
