Did you get to parse de json?

Hi!
i was thinking in buy something to give connection to my arduino. At the beginingn i think i something wired

• , but in my last work, i used a module wifi called Connect One iWifi [1]. The last ones is too much expensive than
• and [3]. I find another wifi module that is cheaper than the other and i can get here in Chile.

So my question... what is better to do? anybody has experience with [4] and the arduino?

Thanks!
Roberto

Is a good idea buy this one?
there is 20 dollars of difference in compare with a ehternet shield with W5100 chip. Or i can buy with confidence?

Thanks for the advice.

CrossRoads, i have updated my location. By the way i'm on Santiago of Chile in South America.

Thank you very much!
I will look and if i have another doubt i will ask here again

Hi all!
I'm coming back to develop projects with my arduino after a pairs of years. I have been buying some components, but i'm in doubt about what i should buy... there is a common kind of component that are usefoul for many common project? What i can avoid? go to the electronic store to buy, for example... 2 resistor of 1omh by say something...
So, any clue? A link for a kit?
Thanks a lot!!
Roberto

JakesSA,
this is the circuit that i have used. I hope that it were clear. I'm not electronic, so i don't know too much the language
I know that "electrically" it is working, because the wifi module answer to a ping and i can browse the admin page.
I have not configured yet the posibility to access via wifi the arduino, so i have not rsolve the problem with the serial conection. I was thinking to use the code that you post to make some test. Do you have an another idea?
When you use the code that you post, how do you send the commands? Because, when i connect the wifi module to the arduino using the TX and RX pins, it give me this problem.
Do you have a msn account, we could chat by there.
Roberto

I use this circuit [0] to connect the RX pin on MiniWifiSocket.
I can connect without problem of power the mini socket wfi and the arduino.

@JakesSA
Did you resolve the problem with the junk character?

Roberto

Thanks for your answer. Yesterday I conclude the same... This allow me to understand another things!
Thank you again!.
Roberto

I have discovered that if I disconnect the pin of TX and RX of arduino, the problem it's avoided.
Now, i'm curious to know what is the reason of this. Anybody know?
Roberto

The image of the circuit is here.

Thanks for the help!

I have the following problem trying to upload a very simple program. This is the program:

avrdude: Version 5.4-arduino, compiled on Oct 22 2007 at 13:15:12
         Copyright (c) 2000-2005 Brian Dean,

         System wide configuration file is "hardware/tools/avrdude.conf"

         User configuration file does not exist or is not a regular file, skipping

         Using Port            : /dev/ttyUSB0

avrdude: Send: Q [51]   [20]
avrdude: ser_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

The program is:

#define BAUDIOS 9600
boolean ejecutar = true;
void setup(){
    Serial.begin(BAUDIOS);
}

void loop(){
  if(ejecutar){
    Serial.println("AT+iRP11");
    ejecutar=false;
  }
}

I have discarded a problem in the hardware, because if only i had the arduino board conected to the usb port and nothing conected to it, the program upload without problems, so I suspect that my circuit it has a problem, (but it is working). The circuit is in the next post (i can upload images with my first post):


I'm not an expert with this, but i thing that it's posible to get the main idea.

Someone can give me a hand?

Thanks a lot!
Roberto

@webtek23
This code work for me. I get info in the serial monitor. I change the numbers of the pins. I'm using an arduino decimilia. I use the pin number 3 and 4 in the analog input. Did you calibrate the sonar and are you getting a correct value or only it is a reference?
Roberto

scurvyrat,
by that i remember, the guys got some problems with one wifi card (if you read the log of the project, will got this info). I suppose that it is not the connect one problematic card.

Jin, thanks for the codes that you have used. I will search for my backup and i will recover this project. For me i make an interface with django to access to the connect one. It was not too elegant (i open a socket direct to the connect one), but it works.
I will try to publish something.
Greets!
Roberto

scurvyrat, I have been using this: http://www.olimex.cl/product_info.php?cPath=76_78&products_id=273

I don't get  the point with the 3.3v.

By the way, this guys use an arduino and ConnectOne. They use a solar panel to energyze the equipment.
