I would like to have an explanation about the use of resistance in the project number 2
spatialship board in the starter kit.
My question is? why the resistance of 220 ohms is used to connect leds to GND instead of connecting resistance to 5V?
I believed that resistance is used to absorb volts that entering into a led instead from 5v , instead to absorb the volts that go out from the leds towards GND?
