OLED with Spark Core
Simple wiring for Basic 16x2 Character OLED - Yellow on Black. https://www.sparkfun.com/products/11987 Some simple soldering is required to mount the display on the breadboard.
I've included a link to a gist in git hub. This won't be needed for long when we get library support in the Spark IDE and infrastructure.
There are two versions of OLEDs firmware floating around and so you'll need to possibly change
lcd = new Adafruit_CharacterOLED(OLED_V1, D0, D1, D2, D3, D4, D5, D6);
lcd = new Adafruit_CharacterOLED(OLED_V2, D0, D1, D2, D3, D4, D5, D6);
if you have a new one.
