I am working on a project in which arduino is required to read the 12v input and perform some action accordingly. But I think Arduino can read only upto 5v AnalogIn. I dont want my board to burn. What should I do?

Use a pair of resistors as a voltage divider, (with the junction of the resistors connected to the analogue pin), chosen so that the highest voltage that you will be measuring is below 5V.
Hi,
What is your electronics, programming, arduino, hardware experience?
Tom.... 
Here is the sch for divider
