Thanks Terry!

Sir!

Im using arduino 0022 and doing my simulations on proteus, what should  I do to put my hex files beside my sketch files. with shift+compile i could find hex on temp files.

thank you! last time,I saw a video, his hex files went to a folder named APPLET....

Hi i have 2 question im beginner ,1 st how do you connec  naxim ICM7218BIJI.ICM7218BIJI. to arduino ,in ds 1307 how can ypi get hour ?

Answer to 1st Question: http://bit.ly/NXaQiO

Answer to 2nd Question:  Learn from the best.

#include "RTClib.h"

DateTime now = RTC.now();

Serial.print(now.hour(), DEC);

And always remember this:

Hmm, dis ist velly eentellesting.

Hello everyone. i am working on Arduino based server project which let you control or monitor instruments; like machine,motor;over internet. I have written code for Arduino DHCP server which turn on/off LED over internet. it woks in local area. For controlling Arduino outside the world I've done port forwarding in my ADSL modem/Router. now the problem is that i am using DHCP internet from my ISP so i need to check whether my IP is changed or not. I am not from pure networking background so i dnt have much knowledge on it. but from somewhere i've found that i need DNS server and an IP updater program. but i am not cleared what to do? please someone guide me i dont have much time i have to submit this project before 15th october 2012.

Thanks in Advance....

Jeremy,

The problem i'm having is that im using an arduino uno with a GPRS shield and with the code set up below, i get a continuos sms message on my iphone that i cant stop, also when the wires i have set up on the Gprs are unconnected i still get sms messages on my phone.

Thanks for your help

//sketch sends a text message if the waterSensor becomes submerged

#include <SoftwareSerial.h>

SoftwareSerial mySerial(7, 8); //gprs shield attached to pins 7 and 8 for software serial connection

const String phoneNumber = "+1609xxxxxxx"; //the phone number of the phone to send the text message to, remember to include the country code before the number

const int sensorPin = 2; //the water sensor is attached to pin 2

boolean flooded = false; //set the flooded variable to false

boolean messageSent = false;

void setup(){

  mySerial.begin(19200); //19200 is the GPRS baud rate, this must be fixed

  Serial.begin(19200);

  pinMode(sensorPin, INPUT);

  delay(500);

}

void loop(){ //we loop through this area

  if (digitalRead(sensorPin) == HIGH){ //if the sensorPin is high, current is being passed into it, so the sensor must be submerged

    flooded = true; //the basement is therefor flooded

  } else if (digitalRead(sensorPin) == LOW){ //otherwise if it has no current

    flooded = false; //the sensor isn't submerged

    messageSent = false; //we can reset the messageSend, so that if it becomes submerged again, we can end another text message

  }

  if ((messageSent == false) && (flooded == true)){ //if we havent yet sent a message, and the sensor is submerged

    sendTextMessage(phoneNumber, "Your basement is flooding [Arduino]"); //we send the text message

    messageSent = true; //we set messageSent to true so that we don't keep sending text messages (this woulld cost a lot of money)

  }

}

void sendTextMessage(String phone, String data){ //sends a text message to phone, containing data

mySerial.print("AT+CMGF=1\r");    //Because we want to send the SMS in text mode

delay(100);

mySerial.println("AT + CMGS = \"" + phone + "\"");//send sms message, be careful need to add a country code before the cellphone number

delay(100);

mySerial.println(data);//the content of the message

delay(100);

mySerial.println((char)26);//the ASCII code of the ctrl+z is 26

delay(100);

mySerial.println();

}

great terry it will be useful to all arduino fans.

Hi There could you please tell me the opposite 4 way plug that fits into

SAMTEC - MPT-04-01-01-L-RA-SD - HEADER, 4WAY, POWER, R/A

Samtec MPT mates with MPS

see the PDF from samtec. http://www.farnell.com/datasheets/452738.pdf at the lower part.
