I think we should regulary update the News section of the forum.
From the description: "Read about the latest happenings to Arduino "
Unfortunately, we barely see any news. For exemple: The News regarding Arduino Uno and Mega 2560 are not in this section.

I know that we should actually get our news from the blog, but wouldn't that leave the "News" forum useless then and wouldn't require to exist?

My point is, that some people don't read about any news regarding arduino except in the forums. These people are looking at the "News" forum for any news, but this section is not update very often.

Shouldn't it deserve a little more attention?
Thanks  smiley-grin
ps: Pardon my English.

Going to try that someday.
Thanks.

Nope.

Hello.
I was trying a sketch in Processing from a friend of mine. We used the exact same code with the same RGB led and same wiring.

The sketch is bringing up a color wheel and when you choose a color, your RGB led become of that color.

http://pastebin.com/XZrDGbFN
Processing sketch


http://www.webdesign.org/img_articles/15053/Color-Wheel.jpg
Color wheel :  (save as "wheel.jpg" in your data folder)  

http://www.arduino.cc/playground/Interfacing/Processing
Using the Processing library v. 0017

and I upload the sketch StandardFirmdata  from the Arduino IDE v. 0021.


So the problem is my RGB led is alway White and does nothing. No problem on the side of my friend.

The only difference we technically have is that he used  the IDE v. 0020  and he have an Arduino duemilanove.

(I have a UNO)

Can anyone solve this mystery?
So far our theory is about the missing FTDI of the UNO.

Alright thanks,

I own you one!  smiley-grin

So far my code was like that:

Quote
int buzzer = 11; //the pin with the piezo buzzer
int v = 0;
char p, *l;
String number;
int x = 0;

void setup()
{
  Serial.begin(9600);
  Serial.println("Frequency: ");
  
}


void frequencyPick()
{
  if (Serial.available() > 0 && x < 3) // data available?
 
  {
   p = Serial.read();
   *l = p;
   v = atoi(l);
   number= number + v;
   Serial.println(number);
   x = x + 1;
  
  }
}





void loop()
{

frequencyPick();
number = 0;
x = 0;
}


With little bugs as you can see. (Infinite loop, infinite resetting number value, etc.) But as I said, that wasnt the most important thing that annoyed me.

Thank you for your time and patience.
edit: I did some research and I understand your code, again, THANKS.

Thanks for you help.

But I feel uncomfortable saying that I'm still getting "echo" in the Serial. (entry: 45  Print: 1- 4   2- 45)

:-/ Thats exactly what I was looking for since yesterday.
I tried some methods with  do/while and if, but I always ended up with a little bit of complication.


I see you edited your post.

well I did made some progress.
Same problem, but was able to finally get a string.

Spend 5 minutes googling the forum to find an answer.
Thanks, but I've spent 2 hours (yesterday) 3-4 hours trying to find how to implement correctly atoi/string, thats why I came here for help.

Anyway, thanks for pointing out some of my errors.

Hello,
I'm trying to enter a number ranged between 250 and 523 in the Serial Monitor. Then, I want the Arduino to sent back the same number (as a confirmation). The only problem is that it see each numbers as separated entries.

So if I write down: 255 I will get three Serial Print saying : Unknown Entry. ( "2" "5" and "5")

Can you point me in the correct direction?
I have read from the documentation that the last character to be printed is transmitted over the serial port after Serial.print() has returned, but that didn't help  :-[

Thanks

I know a way, but in C++ and I thnk its RAM consuming.

What about the Arduino Uno?

Ok merci  smiley-wink

(Pas nécessairement le FTDI. Il n'en a pas dans le Uno)

Je cherchais un moyen de lire des valeurs sur l'Arduino avec mon Mac depuis quelques temps...
Les Mac ne peuvent pas créer des ports Serial virtuels?
Comment utilises-tu le IDE  dans ce cas?

Je suis très confus, j'ai sans doute mal compris  ;D

Si tu cherche plutot à faire tes propre jeux informe toi sur le uzebox.
Sinon, si tu veux faire la console toi même: Arduino. smiley-grin
