Euphonic You Prototype Components

This shows the Spark Core which has been configured as a Smart Things device. Also shown is the Teensy 3.0 which is programmed as a MIDI device to control a sound synthesizer on the laptop. Finally, the Smart Things multi-sensor controls the Spark Core through the Ambience On, Ambience Off application.

Code

Spark Core Firmware

Plain text
This is what responds to HTTP requests from the Smart Things Euphonia device.
/* A Spark function to parse the commands */
int ledControl(String command);

// We name pin D7 as led
int led = D7; 

// This routine runs only once upon reset
void setup() 
{
  //Register Spark function
  Spark.function("ledstate", ledControl);    
  // Initialize D0 pin as an output
  pinMode(led, OUTPUT);
}

// This routine loops forever 
void loop()
{
  // Nothing to do here
}

int ledControl(String command)
{
  if (command == "1") {   
    digitalWrite(led, HIGH);   // Turn ON the LED
    return 1;
  } else {               
    digitalWrite(led, LOW);    // Turn OFF the LED
    return 0;
  }
}

Spark Core Blink Device Handler

Plain text
This turns the Euphonia device (Teensy) on and off.
/**

 */

preferences {
    input("deviceId", "text", title: "Device ID")
    input("token", "text", title: "Access Token")
}

	definition (name: "Spark Core Blink", namespace: "robertgallup", author: "Robert Gallup") {

		main "switch"

	}

}

// parse events into attributes

	log.error "This device does not support incoming events"
	// TODO: handle 'switch' attribute
}

	put '1'
}

	put '0'
}

private put(led) {
    //Spark Core API Call
	httpPost(

        body: [access_token: token, command: led],  
	) {response -> log.debug (response.data)}
}

Ambience On, Ambience Off Smart Things Application

This closes the loop between the multi-sensor and the Euphonia device
