When the switch is on inner leds fade in quicker then outter leds.when switch is off leds fade opposite to switch on. leds are connect in parallel. I figured that by changing the capacitors value determines the fading speed. C2 should be greater then C1 to get the fade effect. My intensions were to make an Arc reactor( Iron man ) fading effect. so any suggestions advice help ideas and criticism will be appreciated much. thanks
