Good O so what do you do with it ? Shoot spots on the wall?WoW.
Yes you got the idea correct, since the title of my post says [average difficulty] and I wrote that this is a quick tutorial, guess what? It's meant to be a tutorial! And for what? For people who are new to programming/processing/arduino. In the process of creating this you can learn how to interface arduino with processing and a mouse. Which consequently means you can try to build more complex/better things than before.
I'm wondering how much power it consumes and will it run on a battery for long.
For what? Its hooked up to a computer for the interface, what's the point of running this on battery?
My laser which looks identical to yours
Hmm where did you see my laser? It's not visible in the picture I made.
takes about three amps
Take a look at my initial post where it says: "get a cheap laserpointer" and not "get a handheld doomsday device"
If you don't have any useful questions please save yourself (and me) the time and don't post anything.
cheers
