			First begin by running the program sample.pde in the folder where the OneWire library is (under example). You should see some messages when you turn on the serial monitor. Make sure you set the correct pin for the sensor at the top of the program.

			Next run the simple.pde program in the DallasTemperature library. You should start seeing actual temperature readings!

			Finally run the program below. It displays the temp on the LCD!

==Introduction==
'''DS1820 digital temp sensor'''
In this experiment we will connect the DS1820 temperature sensor to the arduino, read the temperature and display it on the LCD.

This is a complex little chip. Please check out the resources at the bottom of this page for lots of information!

==Components Needed==
*Freeduino or Arduino or clone
*USB cable for Freeduino
*Freeduino development software - [http://www.arduino.cc/en/Main/Software download here!]
*Solderless Breadboard
*Hookup wire 22gauge solid
*DS1820 digital sensor
*4.7K resistor
*LCD Display

==How to==
#Use the breadboard and hook up the circuit as follows

==Troubleshooting==

Are power and ground set up correctly?

Double check the schematic.
