help: rgb controller by one button to 8 function

[teng2005]

Your variable pinLed determines what mode you are in: RED, BLUE or GREEN so there are three modes 0, 1 or 2. Now you need a fourth mode, so pinLed needs to go to 3.

When pinLed is 0, 1 or 2 you run the code that you have now. When pinLed is 3 you do the fading effect. I have rearranged your code to call a function named oneColor() when the mode is 0, 1 or 2. If mode is 3 a function named fadeColors() is called. There is no fading effect now, it just flashes the three leds in turn.

Give this code a try, if it works correctly with your buttons you just need to write the fade function.

thanks sir its working but i want in fading is the 7 color will be the output like(green, blue,red, yellow,purple,white and skyblue)
