Servo.h library (included with arduino) (SOLVED)

Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created

int pos = 0; // variable to store the servo position

void setup()
{
myservo.attach(D0); // attaches the servo on pin 0 to the servo object
}

void loop()
{
for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}

Hi, I am trying to get the code above going on my sparkcore and I'm very new to this so please forgive me if the questions are a little silly. I have a servo which I think is this one: https://www.sparkfun.com/products/9065 it came in a sparkfun arduino inventors kit. It has 3 wires: red, black and white. I have a separate 2amp power supplied to 5volts on red, ground on black and I have white going to pin D0. The sparkcore is powered by USB on my computer.

I flashed the above sketch to my sparkcore and then I powered up the servo. It does make a little sound when powered up initially. It seems to hum even when idle however so I am wondering if it connected correctly.

Anyhow, I opened up the sparkcore android tinker app and tried controlling pin D0 but I couldn't get it to work. Am I missing something?
