Hi,
By "turning LED reflectorsr" do you mean you're only turning the LED light on/off or are you rotating the reflector with a motor? I think there's some confusion here on that definition.
Also, as a side note since you're using FTDI for programming I'd normally put an 0.1uF ceramic cap between the programming header and the reset pin on the ATmega - as per Nick Gammon's explanation (toward the bottom of that page) - not sure if that part is working for you as it currently is.
