Pcom Understanding electricity

The first week of physical-computing is all about the basics of electricity. From what is Voltage/current/resistance to Familiarizing with different components in use.
These are different components from the Arduino Uno starter kit.

A circuit in a “clean way”:

What is a LED? A Light emitting Diode which allows electricity flow in only one direction. The shorter leg signifies GROUND (-). We cannot just connect any LED to any power – a resistor is needed to allow only the right current go in it. This LED requires a 220 Ohms resistor which have its own distinct colors.
