Accessing the sonar sensor from the Arduino IDE

Now that the HW is connected, you'll want to download a library that supports this sensor. One of the better libraries for this sensor is available at Download the NewPing library and then open the Arduino IDE. You can include the library in the IDE by navigating to Sketch | Import Library | Add Library | Downloads and selecting the NewPing ZIP file. Once you have the library installed, you can access the example program by navigating to File | Examples | NewPing | NewPingExample as shown in the following screenshot:
