So to set the pin #0 LED on and off (which would be pin #3 in Lua) first make it an output:

Turn the LED on with:

And off with:

You can make this a little more automated by running a longer script.

For longer text, pasting can be difficult as the lua interpreter needs a little delay time between characters and also

require CR-LF settings. For that reason you may want to paste each line and then hit return manually.
