I'm a complete novice when it comes to programming so apologies if this is very simple.
I've got a sparkfun dome push button that I want to use to trigger a photo booth. I've managed to wire up the LED to a 12v connector and set it as push to break (i'm going to hopefully set it to pulse after a certain period of inactivity) but I can't figure out how to connect to the arduino without frying it (which I've done to one already).
On pushing the button it should send a keyboard request to the laptop to start the process of capturing the images.
Has anyone done similar or any advise welcome.
Many thanks Ciaran
