I've tried gobetwino, doesn't work with windows 7..Also, I saw a tutorial on youtube by Jeremy Blum about serial communication, and he did it using the language processor, and he said that you can interact with your computer from arduino using any programming language... Now, that being said it should be possible with Lua, so how can this be done with Lua?
The way that quote is written, you put the Lua code on the PC and have it communicate with your Arduino program. If you have any doubt, ask him.
Or you write a maybe-limited Lua interpreter for the Arduino which may or may not not be possible and still what will you code the PC end in?
