functionality first layout later!
asp is not in my Vocabulary...

what do you code it in html or php? you could use mysql database with all the shields...
and use php to notify of pin useage.

+ a adding system would be a simple as a few <input> fields

i can try to come up with something and post it on my website.
i really want to have a new webpage project.
maybe go trough with the arduino sketchs/library upload site and add this to.

if it ok with you i'll use your code.

[______________{ Dutch }__________________________]

I would love to make a dutch forum on my own website if it would be used...

But there are so few of us dutch people that can't read and (maybe crappy) write english.
and if all the dutch people here have questions and can't explain there selfs just ask in your best english and try to get me or anny other dutch guy to help... or start your topic with [NL] or something

or even better try to explain it in english and dutch so that if i see it i can correct your error's so that everybody gets it.


and i want to point out that if i don't understand something that was found in the french or anny other country u could just use google tanslate to translate the whole page.
it's not that great in translating story's or explainations but if your keep in mind google translates (almost) everything literally.
Then its acceptable.

I think my english is quite good.
of course i make misstake's but hé i'm a dutch blond girl...

______________{ Dutch }__________________________[size=10]
dus voor de nederlanders laat het me weten als jullie een nederlands forum willen en ik zal er een aan maken op mijn eigen website al zal er denk ik vrij weinig volk komen om ook echt iedereen te helpen.
en als er al mensen komen moeten er natuurlijk ook mensen komen die de antwoorden hebben en niet alleen vragen stellen.[/size]


Greets SaSaa.

i use notepad++ for writing script then paste them into IDE just because i like notepad++ more clear on the brackets and stuff like that maybe i'll write a plugin to reconize the commands and stuff like that.

ik don't like IDE because of its layout and that is java and sometimes Way to slow.

finally got the time to post my clock code

It works GREAT ! I really love Open Source

thanks Korman.
I'll post my complete code soon

I will try it when I get home in about 9 hours :-P
the digit1 to 4 are just part of my explaination*

I'm able to output it on my LCD's and the serial monitotr but not on the 4 matrices and it really bugs me.

the real problem is that i don't understand how to write it to the display when the numbers are bigger then 9 because it will then take 2 matrices to show the value

the serial monitoris very simple because its as simple as taken from the official example

Code:

// Date and time functions using a DS1307 RTC connected via I2C and Wire lib

#include <Wire.h>
#include "RTClib.h"

RTC_DS1307 RTC;

void setup () {
    Serial.begin(57600);
    Wire.begin();
    RTC.begin();

  if (! RTC.isrunning()) {
    Serial.println("RTC is NOT running!");
    // following line sets the RTC to the date & time this sketch was compiled
    RTC.adjust(DateTime(__DATE__, __TIME__));
  }
}

void loop () {
    DateTime now = RTC.now();
    
    Serial.print(now.year(), DEC);
    Serial.print('/');
    Serial.print(now.month(), DEC);
    Serial.print('/');
    Serial.print(now.day(), DEC);
    Serial.print(' ');
    Serial.print(now.hour(), DEC);
    Serial.print(':');
    Serial.print(now.minute(), DEC);
    Serial.print(':');
    Serial.print(now.second(), DEC);
    Serial.println();
    
    Serial.print(" since midnight 1/1/1970 = ");
    Serial.print(now.unixtime());
    Serial.print("s = ");
    Serial.print(now.unixtime() / 86400L);
    Serial.println("d");
    
    // calculate a date which is 7 days and 30 seconds into the future
    DateTime future (now.unixtime() + 7 * 86400L + 30);
    
    Serial.print(" now + 7d + 30s: ");
    Serial.print(future.year(), DEC);
    Serial.print('/');
    Serial.print(future.month(), DEC);
    Serial.print('/');
    Serial.print(future.day(), DEC);
    Serial.print(' ');
    Serial.print(future.hour(), DEC);
    Serial.print(':');
    Serial.print(future.minute(), DEC);
    Serial.print(':');
    Serial.print(future.second(), DEC);
    Serial.println();
    
    Serial.println();
    delay(3000);
}

how do i get this "Serial.print(now.day(), DEC);" and split the digits if there are 2 :S so i can put in this

Code:

#include <Wire.h>

unsigned char RainbowCMD[5];
unsigned char State = 0;  
unsigned long timeout;

{
  Wire.begin(); // join i2c bus (address optional for master)

i really don't know :S

Hi there,
I'm trying to make a nice clock for the master bedroom.
I got 4 rainbowdouino's with RGB matrixes on them.
it works great.

although I have no trouble trying to display the time of my "ladyada's log shield" over serial.

I want to display the time on the four matrixes so that every matrix just shows one number (only hours and minutes)

But i never worked with a RTC before so hoped to learn something here

If possible i love to have the seconds to but i dont know how.
32x8 pixels is a lot so it should work

Yeah it works...

this is sort of what I had come up with myself but it din't work because of wstring being corrupt.

Thank you all

only problem now is displaying special characters but if you try hard you can get them out/replaced to .

mmm crap made that was it then gonna try it again
Thank you all!

just a quick reply the hole readstring is good and can be displayed on the lcd

just the substring doen'st seem to like me going to experiment a little bit more later today because i'm doing a laptop to DPF thing

This is what i have for now:

I can't get the msg out of the string.

I tried using this:
char end_value = readString.length();
String msg1 = readString.substring(10, end_value - 11);
but it returns nothing...

very annoying...

have confirmed the lcd and ethernet shield working so that aint the problem...

@zoomkat

could you post your complete code?
because i missing some pieces...

thank you

Hello everybody I wanted my wifi robot to display a msg from my web controlling page.

So I'm using a 16x2 lcd with my ethernetshield and since i made a shiel for it taht uses the 11 and 12 pin i had to change them to 8 and 9  because ethernet shield uses 10..13.
I do have almost complete code but i can't get the lcd to display the msg i'll have to catch the msg from a GET response...

String readString = String(30);

  Serial.begin(9600);

simple hello msg

Code:

GET /?msg=hello HTTP/1.1

first 10 can be discarted (i don't know how)
and last 9 can be discarted
problem is the msg is not always the same length.
and i don't know how to manipulate a string.
