It is simple arduino  thermometer project

You Need--

Arduino UNO or any other arduino board

Nokia 5100 LCD Module

Analog Temperature sensor LM-35

Jumper wires

Bread board or vero board


here I use nokia  pcd 8544 - 1.4.3 library ( download library )

after add library You can get code in sample of 8544 library
