que has probado? que codigo? pegalo? lo has escrito tu o de donde lo has sacado?
 has probado los ejemplos basicos que vienen con arduino? webclient?

copiar y pegar codigos no sirve de mucho sin entender que se esta haciendo.

que errores te da?

entiendo que estas empezando y quieres descubrir mundo, yo tambien he estado ahi cuando empece con arduino, pero deberias hacer una cosa, cogete los ejemplos basicos y entiendelos.

intenta entender linea a linea el codigo que has copiado, solo así sabras que estas haciendo. preguntanos que linea no entiendes y te ayudaremos sin problemas.

Utiliza el botón de code en el foro para poner código, sino no hay quien lo lea. Y quita los numeros de linea.
Es tu código? O es copia pega? Sabes q hace?

 

Heke estupendos enlaces muchas gracias

Abre un post nuevo y pon tu codigo y tus averiguaciones hasta el momento

me alegro. en mi primer proyecto grande yo sufrí 2 o 3 meses volviéndome loco por culpa de que había llenado el Arduino UNO.

que arduino usas?
prueba la libreria FreeMem y dinos cuanta memoria RAM te queda libre

a mi tambien me paso esto, puedes usar con regulador lineal a 5V. Yo tengo el mio metiendole 5V por Vcc, hay gente que no lo recomienda y gente qeu dice que no pasa nada, yo lo tengo funcionando 2 años así y funciona.
Metele 5V al pin 5V y prueba si el resto del arudino va bien.

Jantje, its a good idea what you propose, and I have several of those TPLink 703, actually I use one of them to convert Wifi to Ethernet for this same project, so I dont have to deal with wifi shields.
however, I wanted to keep all the programing and hacking on the arduino, so that when reproducing this project I dont need to depend also on the hacked router. Also this way I can use a network cable, with my project, or a router in bridge mode, and the sketch does not need to be changed.
however, thanks for the suggestion.

I believe there is a timeout on the upload execution, the disadvantage of this is that you start loosing uploads if things take a little bit longer than expected.

marca el titulo como SOLUCIONADO.

very interesting how all this is coming.
I also measured my loop timing in my projects, however there is one situation I think has no way of improving the timing. Every 10 seconds I upload information to a server on the internet, so I call this...

Code:

// Make a HTTP request:
        Serial.print("Connecting...");
        if (client.connect(server, 80)) {//if (client.connect())
          Serial.print("connected!");
                    client.println(str);
                    client.println();
                    client.println();
                    client.stop();

It takes around 1300ms to finish, have not found a way to improve it, if any of you know how to.
Also when reading DS18B20 you need to do some delays, that also adds nearly a seconds (I only read them every 5 minutos)

Code:

// ^ is logical XOR,

sp. "^ is bitwise XOR, and potentially unsuitable for use here"

interesting. So its not correctly use? it does work. could you explain AWOL so we all learn from it? thanks

would it be then like this?

Code:

ledState = ~ledState;

I would like to thank you GoForSmoke for that example, I have actually learned quite a bit even from such a short sketch.
I am in the process of trying to start learning how to "optimize" my code. i have big projects but I feel they could be improved by things you mention in your example.

So for example to invert a led I was doing

Code:

digitalWrite(StatusLED_System, !digitalRead(StatusLED_System));

instead of

Code:

// if the LED is off turn it on and vice-versa:
    ledState = ledState ^ 1; // ^ is logical XOR, true if the values are different
    // using logic operations can save a lot of tedious, pain to debug if's

I dont know the actual benefits but the second options sounds like more efficient, dont know why.

I would like to ask you the reason for this changes, the actual improvement it makes, please if you can, give me a hand understanding it.

changed time variables to be ALL unsigned longs, as they should be.

what are the benefits of defining it as "unsigned" as oppose to just long?

added UL to numbers being assigned to unsigned longs as should be.

I have never added the "UL", where should it be added? why?

I have used google but im not hitting the right buttons I guess.

Thanks for your help, hope more examples are "optimised" as you just did with this one.

puedes guardarte el tonito para tu vida personal/social o lo que tengas.

aunque existen miles de proyectos con arduino no siempre es posible encontrar justo lo que quieres hacer ya realizado. si fuese verdad que has leido tanto y visto tantos videos sabrias como funciona un xbee, sabrias como funciona un arduino y sabrias como funciona un jostick. por lo que preguntarias algo mas concreto, o habrias empezado a escribir tu codigo y pedirias ayuda con algo que no sabes hacer.

ademas tu mensaje original dices

Necesitaría ayuda de como configurar los dos XBee para que entre ellos se entiendan

si no has encontrado en google y youtube como hacer esto, deja el arduino a un lado y empieza con internet ABC. ves yo tambien se !
