Howdy,
My project involves using a single switch state change to automate a 1/4" = 1' model between different "scenes." Using the servos to move walls, I want to have control over the lighting using RGB LEDS. Lastly, I want them to fade to the next state, instead of simply snapping on and off. The issue I have run into, is that in state change, the servo and LED function perfectly, but then the LED snaps back to it's prior state, only to repeat the fade. What confuses me even more, is that it only repeats once. Could anyone shed some light on this? Thank you!
Here is the original code for RGB LED fading by AdaFruit: http://ardx.org/RGBANA
I also used Korman's VarSpeedServo Library

your's isnt so bad, crashoverride61088. And I do love you giving us a whole video of everything.
