Have anybody figured a way to do Two-Way communication on this scheme?

Thanks

Well, I was thinking in trying to build it myself.

The hardest part would be to find parts to build  smiley-cry

But would be a good experience! It's using a 3A voltage regulator!
How much current does a tiny servo uses?

Hi, I would like to know if any one know about the eagle file to this board,
as I would like to make some for me, to make my first try with SMD components.

In this pdf file, it has all the schematics, but would be a lot of work to re-build the board, and
if there was it available on the web, would be easier.

Thanks smiley
5  Using Arduino / Interfacing w/ Software on the Computer / Re: Arduino stoped sending data to processing on: May 19, 2011, 07:12:29 am
But i wont face easy access to the arduino board nor the macmini,
so a way i could fo something like

if(myPort1.available()>0) {}
else{
myPort1 = new Serial(this, serial1, 115200);
   myPort1.bufferUntil('\n');

}

then it would try to re-open connection automatically

But i'm not sure the problem is this, still trying to figure out the problem.

Could slowing down the transfer speed help?

But is there a way in processing to re-open serial connection if it failed?

Thanks

Hello, i am having the problem with arduino and processing.

I have a arduino mega with Sharp IR sensor sensing data to Processing connected to a Processing program running on a MacMini.
The serial speed is 115200,
but the problem is that when I touch the board, I think the USB cable isn't tight enough and it looses connection, so that the Arduino stops sending data to the computer.

So the only way to fix it would be re-opening the processing app.

Any way to fix this, maybe somehow to reset connection on the go of something.
Thanks

Ahhh, I am going to milan on august.  smiley-cry Too bad, I would really like to go to this event.
Hopefully will be another or something like that from august till end of january.

Thanks, congrats for organizing this!!  smiley-grin

Olá pessoal, aqui vai uma boa noticia,
acabo de criar o fórum Eletrônica Livre, com a idéia de expandir a difusão da informações sobre eletrônica e software.

http://www.eletronicalivre.com.br

Cada vez mais a comunidade "maker" esta crescendo no Brasil, as pessoas estão se interessando sobre eletrônica, o ensino dela esta cada vez mais presenta nas escolas.
Porém não existe nenhum lugar que tente juntar todo o pessoal, todos que possuem blogs, que postem seus projetos, e ideias no forum também.
Vamos ajudar a divulgar o forum e fazer de lá, uma nova comunidade.
Conto com a colaboração de vocês!
Um abraço

daniel

ah, that's the difference then

I used a part of the code found on arduino.cc website.

To make the LED fade, I used the function delayMicroseconds

worked well

Code:
   for(i=1;i<=1000;i++){
      digitalWrite(j, HIGH);
      delayMicroseconds(i);
        digitalWrite(j, LOW);
        delayMicroseconds(1000 - i);
    }

one question,
why the arduino function analogWrite only work in 6 pins?

I needed to use 7 PWM ports, so I wrote new function so that I was able to use up to 14 PWM pins.

Thanks

i think its a bug/problem with the array i was using, made a different way and it worked smiley-razz

Hi, I was playing with the RTC timer, the code was working great, then I wanted to add a temperature sensor, a code that by itself it works. Bu then when I merged the two codes, its giving a error:

Code:
In function 'void loop()':
error: expected primary-expression before '=' token

on line 127 from pastebin

does any one knows how to fix this? thanks  smiley

Yeah, I know C can be quite complicate to communicate with serial. Do you know where I can get some information on how to communicate arduino with VB or Delphi? Or maybe even with processing (can I build some executable program for example *.exe on windows, that would communicate with arduino)?

Thanks mate
