Distance sensor

Hi, I am planning to make a distance sensor and already procured ultrasonic, HC-SR04. Kindly let me know what all need to be procured in order to get the distance directly into the computer.

thanks

Over 3 million Google hits for "hc-sro4 arduino" and lots of hits on the site here in the Playground.

Some people require spoon feeding....

A micro controller might help.

You can use a $3 Pro-Mini if you have an FTDI Basic to load the code. Otherwise , you can use almost any other arduino.
