Hello, I need something, which could move a small thing, for example a LED diode, in 2 dimensions, on a flat screen. By screen I don't mean an LCD screen, I mean a plain flat plastic screen.
So that I could use computer to move it, by passing two numbers (x and y) to a function in its API? The screen will be 40cm x 20cm, maybe less. It should not have anything that grabs, the diode should be firmly attached to it.
It can be simple and cheap, only capable of holding a small thing like a single diode.
The speed should not be fast, maybe 1 or 2 cm/second.
How this thing is called and do you sell any of them? Thank you.
