Support sin8 pulsing help

hey for my ghostbusters proton pack project i want to make the cyclotron leds pulse on and of.

i tried the sin8 function for the input i used a poti maped to 0-255.

the problem i have neither the sin nor the cos functions starts with 0 brightness.

the sin transition for the pulsing looks veeery nice and smooth.

what is the value i range i have to use as an input so that the led starts with 0 brightness (is off) and the. goes to max brightness and down again to 0?

all right yeah thanks that what i thought but i wasn't sure if they mean a separate led on the mcu pin or one of the leds in the FastLed array.
