Upload the sketch to the Mega before you attach the shield.

I'm not at home at the moment so I can't check things for myself, but by the look of it there are a couple of jumpers next to aerial connector which I think allow you to select the serial connection.

You are using the SoftwareSerial library to communicate with the SIM900 via pins 7 & 8. I found the following on the Software Serial page:

Quote
Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69).

Not 7 & 8.

I don't know if your SIM900 has the facility to use pins 0 & 1, then you can use Serial to talk to it, but you can't then communicate with the PC you are using.

Have a look at the 'Blink without delay' example.

arduino, and a facial recognition sensor

Erm, if the idea is to do one with the other the Arduino doesn't have anything like the resources required.

The Arduino could look after the motors and the travel limiters...

That reads almost as well as some of the spam I manage to get to read on here before the mods delete it!  smiley-wink

Thank you lar3ry.  I'd suspected the first part, the second left me - well, we have an amusement game called Whack-a-mole...

And it depends on what the thing is that you plan to mount it on. Does it create electrical interference? I presume there is some sort of motor on it?

Depends on distance. Bluetooth was designed to connect personal items together so has a limited range, personal experience when streaming music to bluetooth headphones in the house is about 10-15 feet.

Arduino Uno and GSM/GPRS shield. Search for the latter, lots of examples.

I'd like to be able to help but I haven't a clue what you are on about. Could you rephrase the question so it's more suitable for an international audience?

And it pays towards this forum.
148  Using Arduino / General Electronics / Re: arduino compatible GPS on: March 04, 2014, 01:53:04 pm
GPS? Weak signal? Where are you? The signal comes from satellites so I would have thought it should be fairly even across major land masses / the globe.

You could give http://www.seeedstudio.com/depot/contact_us.html a try for starters?
150  Using Arduino / Displays / Re: Arduino Uno + SeeedStudio Touch Shield + SeeedStudio SD Card Shield on: March 03, 2014, 04:44:41 pm
Have you tried contacting Seeed about the problem?
