yes now the main problem its the pointer

Code:

#include <SPI.h> // needed in Arduino 0019 or later

// The includion of EthernetDNS is not needed in Arduino IDE 1.0 or later.

int count;

 void alarm()

the void loop need to have an open brace.....

now that problem has clear, and the main problem now its that im using and incorrect call of the pointers

y see that mistake sorry if i didnt see it.....

and if i just call msg as an char pointer and not an array????

like

Code:

char *msg;

still the compiler says im wrong in the if funtion

Code:

#include <SPI.h> // needed in Arduino 0019 or later
#include <Ethernet.h>
#include <Twitter.h>

// The includion of EthernetDNS is not needed in Arduino IDE 1.0 or later.

yes, but i need an array with pointer, so in the switch case depending on the counter, the pointer msg will be referenced to the array with the message

Code:

char* msg

its the pointer i need..

 i used that because IDE told that that if i use

Code:

char* msg[];

then the zise its unknown,

still the error says that i need an initializer before if  functions....

also doesnot allow me to use the normal { on the start of the void loop()..... so im not sure where its my mistake... maybe i have many of then

this is my code but i doesnt compile, i cant find the error...

i dont need the serial monitor, but, the problem its that until i dont open the serial monitor arduino wont post anything....


and sorry for my ignorance, but why would i need a debounce?? i just need to recognize the change of state on the pin, so if it bounce, until only post one msg its ok for me....

and for the twitter error for posting the same msg i think that using a counter and 5 different msgs in a switch sentence, and the variable

Code:

char msg[]

should be declared as a pointer...

do u think this make any logic???, if so later this day i will post a program to do that...

also thanks for your help it really helps me a lot

thanks everyone for the help, i will try more a little late.

And for the variable char msg.... the lib of this code has tobe declared as char.... maybe i can post millis()... but i will have to study that

Try this out there is no debounce of the pin Interrupt 0 is digital pin 2 on the Uno baord

Code:

#include <SPI.h> // needed in Arduino 0019 or later
#include <Ethernet.h>
#include <Twitter.h>

// The includion of EthernetDNS is not needed in Arduino IDE 1.0 or later.
// Please uncomment below in Arduino IDE 0022 or earlier.

} 

the problem im still trapped its that still the code post only when i open the serial monitor in the IDE, only that this time it waits untill the led turns on.... but its possible to change that i don need to open the serial port???... i dont need any status msg on serial monitor, i mean the arduino will never be connected to a computer to run this program.....

i know how to do that, the problem is that i cant change how to post a msg without opening the serial port

Buenas a todos y bueno sigo trasteando el ethernet shield y encontre como hacer post con el twitter que me parecio muy interesante, el problema es que quiero que el arduino haga un tweet cada vez que un pin cambie de estado LOW a HIGH, ahora el problema es que el programa que encontre aqui publica un tweet cada vez que abro el puerto serial mendiante el IDE de arduino, por lo cual en mi muy basica experiencia no he logrado cambiarlo, lo segundo es que twitter no me deja hacer el mismo tweet 2 veces por lo que reconoce es un mensaje duplicado, alguien que tenga experiencia en esto que me puead dar un pequeño empujon??

el codigo que uso es el basico

Code:

#if defined(ARDUINO) && ARDUINO > 18   // Arduino 0019 or later
#include <SPI.h>
#endif
#include <Ethernet.h>
//#include <EthernetDNS.h>  Only needed in Arduino 0022 or earlier
#include <Twitter.h>



byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 10, 0, 0, 177 };
Twitter twitter("<<< mi token>>>");
char msg[] = "mi mensaje";

void setup()
{
  delay(1000);
  Ethernet.begin(mac);
  Serial.begin(9600);
  
  Serial.println("connecting ...");
  if (twitter.post(msg)) {
    int status = twitter.wait();
    if (status == 200) {
      Serial.println("OK.");
    } else {
      Serial.print("failed : code ");
      Serial.println(status);
    }
  } else {
    Serial.println("connection failed.");
  }
}

{
}

i still have no posted the changes that NIck suggested....

so if i attacht it to an interrupt and read the rising, the arduino will know that, i see that error, thanks, but how can i change that arduino knwos that state and post the msg without open the serial monitor???

hi all...

i just foun this code but maybe im not editing it right....

what i want with the code its ust to simple post a tweet every time my led turns high....

but have many troubles, for example the code just post when i open serial monitor, second when i change the code for the led input, then it doesnt post anything,
and last, its that twitter does not acept my msg cos it said its the same tweet, so how can i change that
