Aim: Display RGB color with LED

Digital 11,12,13 are here defined as led output

The program starts when the green flag is pressed.
-When the key a is pressed, the LED which is connected to the digital 11
will start blinking for 10 time with a 1 sec  delay timing.
-When key q is pressed the LED of digital 12 will in turn get activated for 
the same amount of time.
-when m is pressed the message stop is broadcasted which calls another function
to turn all LEDs OFF before to stop all scripts.
When p is pressed all three (3) color will successively turn ON and OFF continually.

Notice

The LED is a common anode Led therefore  when it receives 0 it will turn ON  and when it receives1 will turn OFF
