Built-in webcam

I had my laptop build to include a webcam. I recently purchased a Logitech webcam because I can move it around. During the installation of the Logitech software I remember a screen prompting me to check which webcam I want to use - I checked the external Logitech webcam. I now want to go back to the build-in webcam.
How do I do this? (I am a total computer novice).
Thanks
 
In skype, go to an old conversation with a contact and look for the symbol resembling connectivity bars.

This should bring up a popup' Select webcam.

From there you can change the webcam in use.
