Linkit building prototype showcase lights

About:

Let's suppose you have to get funding for a building project and your potential funder(s) is coming to see a prototype. One of the best ways to convince them is to, after explaining everything, turn off the lights and have the building beautifully lit. Why not use a small Linkit 7688 Duo for the cause.

Setup:

Once you have your prototype (or lego building etc.) all you have to do is connect the pins as follows:

Red -> 9, Green -> 10, Blue -> 11, and Ground -> GND.

Code:

In the code; r, g, and b; are the pins used for setting the color of the led. And re, ge, and be; are variables used for the operations. i.e. analogWrite(r, re); is write variable re on pin r.

The fading starts by going from red to green. Just increase green and decrease red.

 while (ge < 255) { 
   ge++; 
   re--; 
   analogWrite(r, re); 
   analogWrite(g, ge); 
   analogWrite(b, be); 
   delay(20); 
 } 

Then green to blue.

 while (be < 255) { 
   be++; 
   ge--; 
   analogWrite(r, re); 
   analogWrite(g, ge); 
   analogWrite(b, be); 
   delay(20); 
 } 

And finally from blue back to red.

 while (re < 255) { 
   re++; 
   be--; 
   analogWrite(r, re); 
   analogWrite(g, ge); 
   analogWrite(b, be); 
   delay(20); 
 } 

Then just repeat!
