///////////////
// Pin Setup //
///////////////
// Setup reference variables for our pins:
ledPin <- hardware.pin9;   // Lonely red LED

// Configure our pins:
ledPin.configure(DIGITAL_OUT);        // Simple digital output

/////////////////////////////////
// Agent Function Declarations //
/////////////////////////////////
// setLed will turn the lonely red LED on or off.
// This function will be called by the agent.
function setLed(ledState) 
{
    ledPin.write(ledState);
}


// setUser will print out to the log the name of the LED changer
// This function will be called by the agent.
function setUser(suspect)
{
    server.log(suspect + " set the Lights.");
}

// setTimer will turn the LEDs off after a specified number of seconds
// This function will be called by the agent.
function setTimer(time)
{
    if (time != 0)
        imp.wakeup(time, ledsOff); // Call ledsOff in 'time' seconds.
}

///////////////////////////////////
// Important Agent Handler Stuff //
///////////////////////////////////
// Each object that the agent can send us needs a handler, which we define with
// the agent.on function.  The first parameter in agent.on is an identifier 
// string which must be matched by the sending agent. The second parameter is
// the name of a function to be called. These functions are already defined up
// above.
agent.on("led", setLed);
agent.on("user", setUser);
agent.on("timer", setTimer);

//////////////////////
// Helper Functions //
//////////////////////

// ledsOff just turns all LEDs off.
function ledsOff()
{
    ledPin.write(0);
}
