After a couple of days off we are back on the air. Now we have three functions:

void LedOn(); void LedOff; boolean LedIsOn();

This last one returning 0 or 1 depending on led state.

About the coding standards, we've decided to go with google's C++ coding style guide, aiming to use cpplint.py to stylistically validate the source code.

There is a lot to be done about calling functions, passing arguments, raising errors such as malformatted JSON and so on, but anyway, on step at a time.

Action points:

1. Create function definition - 1 argument, return type void.

2. Test cpplint.py on ProofOfConcept2.ino.
