Add to LED example - making other RGB Colours

[Hwerow]

I have no idea about pull requests so here is my suggestion to add to the Basic LED Example in the loop
// Define CYAN color (R: 0, G: 100, B: 100)
analogWrite(CYD_LED_RED, 255); // Turn off red 255 ie HIGH
analogWrite(CYD_LED_GREEN, 155); // Adjust green intensity (100/255 = 39% , 255* 39% =~100 , Inversion = 255 - 100 = 155)
analogWrite(CYD_LED_BLUE, 155); // Adjust blue intensity ( ditto )

This is a bit tricky as the LED intensities need to be inverted to suit the logic

Cheers
