Temperature Display

Other Hardware Sensors
1

I connected the DS18B20 sensor as the image shows but i don't know how to display the temperature.Please help me.

What have you tried? Did you write a sketch?

3

I don't know what to write.

4

Have you written any sketches (code) at all?

This is what i have written.

void setup()
{
  Serial.begin(9600);
}

void loop()
{
   Serial.print(analogRead(2));
   delay(1000);
}

Please click my link and read, because your way off

Your link didn't help me.

search some more because my link really explains everything....

just search arduino ds18s20

Your link didn't help me.

Do you have a question? Why wasn't the link helpful? That library works well, I use it all the time. It comes with examples that should get you barking up the right trees.

I tried the code but the only thing i get from the serial is "No more addresses".

Please post the code you tried.

I hadn't noticed your link.Thank you.This code works well.

#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into pin 2 on the Arduino
#define ONE_WIRE_BUS 2

// 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);

void setup(void)
{
  // start serial port
  Serial.begin(9600);
  Serial.println("Dallas Temperature IC Control Library Demo");

  // Start up the library
  sensors.begin(); // IC Default 9 bit. If you have troubles consider upping it 12. Ups the delay giving the IC more time to process the temperature measurement
}


void loop(void)
{ 
  // call sensors.requestTemperatures() to issue a global temperature 
  // request to all devices on the bus
  Serial.print("Requesting temperatures...");
  sensors.requestTemperatures(); // Send the command to get temperatures
  Serial.println("DONE");
  
  Serial.print("Temperature for Device 1 is: ");
  Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"? You can have more than one IC on the same bus. 0 refers to the first IC on the wire
  
}

Good deal. BTW, nice picture in the original post, what was that made with?

Looks like it was drawn using http://fritzing.org/

well worth a look at, it too is open source and there are loads of additional drawing libraries to download.

Thanks, I was wondering if it was Fritzing. I'm a couple releases behind, haven't played with it much. Will have to get the current version.
