Hi, from your code, the twitter client doent compile,
it says that there is a problem on line 102

  if (es.ES_find_key_val(str,kvalstrbuf,10,"mn")){

with the error:

 In function 'int8_t analyse_get_url(char*)':
error: 'class EtherShield' has no member named 'ES_find_key_val' In function 'void loop()':

Don't know what to do. Thanks

Yep, I will try =)
thanks

No, im not the same webserver software, but basically the same, apache... php.

I own a dedicated ubuntu box, and when I try the code by hand
ex: /daniel/save.php?pwd=segredo&temp=10

it works.

I dont think the problem is with the server,
but somehow the data is not leaving my home network, somehow to add the router IP and gateway. But im new to ths code and dont fully understand it yet.

Thanks

Hi, i'm using the <etherShield.h>,
I was able to write data on a webserver hosted on my computer, but when I tried to change the server from my computer to my dedicated webserver, is seems to not write any data.

My code is here http://pastebin.com/m441e38e6

If anyone could help! Thanks

im doing a delay(1000) before the end of the loop()

should I just decrease the delay and use a
  buttonState = digitalRead(buttonPin);

or is there any better way of doing it?

another question,
I have 3 buttons,

I want to do like, if I press two at the same time for like some seconds it will able to change the hour. My code for that is bit ugly, but this is the idea

Code:
 if(b1==HIGH && b2==HIGH && b3==LOW) {
    if(activate<400) {activate++;}
  else {hour++;}
  }

i would like to know how would you do.
thanks  smiley-wink

Hi, I was looking for information related to interruptions, but couldn't find a answer for my question. I think it's not that hard to solve.

I'm making a LCD + RTC + Temperature Sensor project.

I want to make the time configurable using buttons.

I want to use 3 buttons that when pressed do something, but there is only two interruptions, what would be the solution?

also, im making something like

Quote
void valor() {  
  hora++;
}

to add hour when its pressed, but it usually ads way more then 1 hour everytime. Any idea how to fix this too??

Thanks

yes, it worked

changed the cable and worked

thanks =)

p1 is the 2.5mm audio jack =)

but its taking pictures even if the cable is connectect to nothing, just one site on the camera

Hello, I was trying to connect my canon XSI to arduino using a p1 cable and an phototransistor 4N28.

The thing is that when I connect the p1 connector on my camera, and I turn it on, it autimatically take a photo and does nothing else.


Does any one know where can I get more information on how the extarnal shutter works??

thanks

yes, my idea is to have the sensor on a servo scanning the area with something like 120ยบ.

so its better a narrow sensor?

Hi, I want to build a robot that will on and change directions when there is an object on his way. I`m thinking about buying a Ultrasonic Sensor,
but I'm not sure which one to buy.

Maxbotix LV-EZ0 -- Maxbotix LV-EZ4

the 0 have a more spread width of band, and the 4 have a strait width. Im just wandering if you guys have any idea in which one is the best for the project.

Thanks

Hey, I would like to save some information provided by arduino on a usb stick, does any one knows where I could get some information?

I want to be able to read a information and save it as txt on a usb.

thanks =)
