/*-------------

This program will toggle two led lights. Green led at D0 will remain flashing when turned on.
It wil blink red led at D1 on and off every second.

-------------*/


// First, we're going to make some variables.
// This is our "shorthand" that we'll use throughout the program:

int ledgreen = D0; // Instead of writing D0 over and over again, we'll write ledgreen
int ledred = D1;  //led red

bool success = true;  //variable to hold whether Jenkins build scucess or not
int ledToggle(String command);

// Having declared these variables, let's move on to the setup function.
// The setup function is a standard part of any microcontroller program.
// It runs only once when the device boots up or is reset.

void setup() {

  // We are going to tell our device that D0 and D1 (which we named ledgreen and ledred respectively) are going to be output
  // (That means that we will be sending voltage to them, rather than monitoring voltage that comes from them)

  // It's important you do this here, inside the setup() function rather than outside it or in the loop function.

  pinMode(ledgreen, OUTPUT);
  pinMode(ledred, OUTPUT);
  Particle.function("toggle", ledToggle);
  
  //At the setup we will light up the green led
  if(success){
      digitalWrite(ledgreen, HIGH);
  }

}

// Next we have the loop function, the other essential part of a microcontroller program.
// This routine gets repeated over and over, as quickly as possible and as many times as possible, after the setup function is called.
// Note: Code that blocks for too long (like more than 5 seconds), can make weird things happen (like dropping the network connection).  The built-in delay function shown below safely interleaves required background activity, so arbitrarily long delays can safely be done if you need them.

void loop() {
  
  //blink the red led if status is set as failed
  if(!success)
  {
        digitalWrite(ledred, HIGH);
        delay(1000);
        digitalWrite(ledred, LOW);
        delay(1000);
  }
}

//Led toggle function we expose to api.particle.io
int ledToggle(String command) {
     if (command == "red") {
        digitalWrite(ledgreen, LOW);
        digitalWrite(ledred, HIGH);
        success = false;
        return 1;
     }
     else if (command =="green") {
        digitalWrite(ledgreen, HIGH);
        digitalWrite(ledred, LOW);
        success = true;
        return 0;
     }     
     return -1;
}
