Lua is not Arduino !!!
Lua has much richer references it allows free programming, which you won't find in Arduino - the environment for testing modules.
Lua has a similar syntax to Pascal, Basic, so just find an example for these languages, and you will be able to port it to LUA without problems
Another thing, the example posted for Arduino is plagiarism, an available version written in Proton 24!!!
