Thanks for the link. I checked that out before, but I am not that experienced in Arduino yet 
I seen another article where you can simply use a basic off/on switch, thru the pins, thru a 3.5mm cable, similar to the unit Canon sells. Just not sure of the volts to send, and how long to pulse it etc...
Anyone else out there can help really quick? thanks 
Example of the unit they sell
