First post and Ardunio project.
I used the KS0108 Lib and the DallasTempature Library for this project. Sorry but no pictures I am camera poor at the moment.
I did this same project with a PIC a year ago and wanted to compare.
I give this round to the Ardunio, alot less code and cussing. 
Still a work in progress, but here it is
/*
* GLCD And Dallas One Wire Sketch for Ardunio Mega
*
* Test code for the Arduino KS0108 GLCD library and Dallas One Wire Libaray.
* Very simple code to display the ouput of 2 DS18S20 sensors
* My plan is to expand the code to allow for an unknown # of sensors and graph the average.
* Ted Crafton 17-07-2010
* Fell free to use as you see fit. I borrowed code from the examples in the Libraries

// Data wire is plugged into port 42 on the Mega, if you use a different one change it here.
#define ONE_WIRE_BUS 42
// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
unsigned int iSensor = 0;
unsigned int icount = 0;
void setup(){
iSensor = 0;
GLCD.Init(NON_INVERTED); // initialise the library, non inverted writes pixels onto a clear screen
GLCD.ClearScreen();
GLCD.DrawBitmap(ArduinoIcon, 32,0, BLACK); //draw the bitmap at the given x,y position
GLCD.SelectFont(System5x7); // switch to fixed width system font
countdown(5);
GLCD.ClearScreen();
Serial.begin(9600);
//Start up the Dallas Lib
sensors.begin();
iSensor = sensors.getDeviceCount(); //Get a count of the number of sensors on the wire
}
void countdown(int count){
while(count--){ // do countdown
GLCD.CursorTo(0,1); // first column, second row (offset is from 0)
GLCD.PutChar(count + '0');
delay(1000);
}
}
void loop(){ // run over and over again
icount = 0;
//Send a request to get the Temps on all Sensors
sensors.requestTemperatures(); // Send the command to get temperatures
GLCD.ClearScreen(); // clear the screen
for(icount = 0; icount < iSensor; icount++){
GLCD.CursorTo(0,icount + 1); // positon cursor
GLCD.Puts("Temperture= ");
GLCD.PrintNumber(sensors.getTempFByIndex(icount));
delay(2000);
}
}
I wanted to be able to hook up a number DS18S20s to a bus and have the tempature read and then dispaly them on the GLCD. I could have done it with an LCD, but I plan on graphing it so GLCD. I decided to use a number of sensors to get an average Tempature. I have 4 sensors and they have a spread of +/- 5 degrees.
I found the forum here to be very helpful, if a little messy.
Hey the smoke stayed in so I must be on the right track.
