Hi Tom,
Thanks for the welcome! Ooops sorry about that 
Now that I have been able to isolate and track specific colors through Visual Studio and a webcam, I would like to have an LED/buzzer module/circuit to indicate that the specific color has been identified.
Laptops don't have GPIO pins so I will need to use the USB/com port to communicate with an Arduino board (which has the output pins) which will in turn produce a digital on/off output to power a small LED/buzzer circuit. Can anyone please point to me on what particular topics or references to read up on seeing as I'm fairly new to Arduino? Thanks and have a good day all.
