Need a little help. If I have done the table correctly I should need a 1 ohm 2 watt resistor on my activation switch. I have a Nano Biscotte v4 with the 18650 3.7 volt battery with the 2 neopixel strips. I just want to make sure I am correct on this any help would be greatly appreciated.

Is there an LED in your switch? If so, what color? If not, then you shouldn't need a resistor.

Unless you are doing something pretty interesting, the LED in the activation switch should only be 20ma, and you would only need a 1/8watt resistor (actual dissipation is about 0.01 - 0.04 watt, depending on the color)

I’m using a 2 prong momentary switch that comes with the graflex kit.
