Find existing schematics for import

I have a project that involves several existing projects from the Arduino and similar libraries. They are:
AC phase control
DHT22 Temperature sensor
Relay control glacialwanderer.com/hobbyrobotics/?p=9
LCD display playground.arduino.cc/LCD/SC2004CSWB

You can probably guess what this is.
I would like to make a custom PCB, and would like to document the project in schematics. Is there a source of existing Fritzing files (specifically the above), that I can pull from and merge, in order to save time? I see some example Fritzing sketches, but did not see the above.

Thanks!
