RGB Led Colors Switcher From Cayenne App

In this my first project with Cayenne App, I seek to control a Led RGB to display color combinations. While the Cayenne App requires an additional module (just buy in a few weeks) to control an analog output (PWM), I have tried to use the digital output, so only 7 colors shall be available (the same is something useful). Besides there is no specific Widget for controlling an RGB LED (as if have Blynk), but I hope this project will help to encourage to create.
