How to make a 3D Constellation with LEDs and Resistors

When you look up at the night sky, have you ever wondered why some stars are brighter than others? Luminosity and distance are the two main factors that effects star's visual brightness. In this project, you will learn how to make a 3D constellation, The Big Dipper, based on their distance from the earth, and use resistors to simulate the real luminosity difference of the seven stars. No coding required.
How to calculate the resistors from luminosity, please check:
