241  Using Arduino / Project Guidance / Re: project involving a photocell sensor on: April 27, 2013, 03:29:47 pm
A photocell is pretty easy to connect to an arduino.

The next part would be GSM so you can send text.  This one looks easy to use, https://www.sparkfun.com/products/9607

Are you printing "!!!" anywhere in your code?

If you haven't noticed, if the poster is wrong or has a mistake in their post, someone everyone will point it out.
245  Using Arduino / Programming Questions / Re: digitalWrite with else/if complication on: April 25, 2013, 03:44:09 pm
Code:
if(sensorValue =  0) {

Needs to be:

Code:
if(sensorValue ==  0) {

'=' is an assignment, '==' is equal to.
246  Using Arduino / Programming Questions / Re: Arduino Mega 2560 GPS (problem) TX, RX on: April 25, 2013, 03:37:30 pm
You need to change:

Code:
gpsSerial.begin(9600);

to

Code:
Serial1.begin(9600);

Then, make sure you connected the GPS to pins 19 (RX) and 18 (TX)

NOTE:  Make sure you change all 'gpsSerial' to 'Serial1'!

Post your test sketch.

Yet, he's right, the 5V and GND pins need to be switched on the ICSP.
250  Community / Bar Sport / Re: Anyone using Arduino official wifi shield? A lot of questions and no answers. on: April 25, 2013, 10:16:47 am
Sorry liudr, if I knew anything about the shield or even owned one, we would troubleshoot it together..

I get spam in Chinese all the time.. 

Wizdum, that is a brilliant email reply!
252  Community / Exhibition / Gallery / Re: "Security" System = Arduino+PIR+LCD+DS1307 on: April 25, 2013, 10:05:08 am
I agree, with cycle, I come on this forum a few times a day and this is the first time I have seen this post.

Anyway, congrats on the working system!  You should post up a little tutorial on instructables or somewhere.  Lots of people have trouble getting a "security" system working.

I am actually glad to hear that.  BatchPCB was terrible the last several months..  Just hope Laen can keep up with the new demand..

I think everyone was waiting for Google to post a reply, but I don't think it's going to happen.
