-# Spark - Blink
-
-For this example, we're going to connect to a Spark Core and make the LED on
-pin D7 blink on a 1-second interval. Before we start, make sure you've got the
-`cylon-spark` module installed.
-
-First, let's make sure to load the Cylon module:
-
-    Cylon = require '../..'
-
-After we've got that done, we can start defining our robot:
-
-    Cylon.robot
-
-We'll have a singular connection to a Spark Core, using the
-previously-mentioned `cylon-spark` module. We'll also have one device, the LED
-on pin D7.
-
-      connection:
-        name: 'spark', adaptor: 'spark', deviceId: '', accessToken: ''
-
-      device:
-        name: 'led', driver: 'led', pin: 'D7'
-
-Those are all the components for our robot, so next we'll define the work. All
-we're going to do for this example is tell the LED to toggle every second.
-
-      work: (my) ->
-        every 1.second(), -> my.led.toggle()
-
-And with all those pieces in place, we can tell the robot to get started:
-
-    .start()
