Hello,
Im new to all this. My goal is to create a rotating chaser circuit to light a large scale model of the Jupiter 2 spacecraft from Lost in Space.
The idea is to have 32 Leds in a chaser effect with 4 channels of 8 Leds at a time. The Leds are laid out in a circle of with 8 groups of 4 Leds. Based on the arrangement it would be challenging to wire them in series. I will be using a 9-volt plug- in power supply with an output of 1-amp. There will be other lights for the interior of the ship.
My question is resistors on the positive side of the Leds. Im unclear if I should treat each Led as if its wired separately and use 1 resistor per Led or if Im actually using a parallel arrangement. My 680 ohm resistors are based on a 10 mA led that drops 2.2 volts.
A very basic question but Im confused. Finally any other issues or advice on my circuit would be appreciated.
Thanks.
