  Try to change the RGB Led’s color to Red, Green, and Blue. 
  Add a blinking loop and see what will happen. This example code is in the

import SwiftIO


// initialize the blue LED
let led = DigitalOut(Id.BLUE)

while true {
     // The code here will run all the time.

     // Set Blue LED off
     led.write(true)
     sleep(ms: 1000)    // Interval of LED blink (milliseconds)
