How to light LEDs with Arduino without having any resistors

WebResistance is measured in ohms, often written as the symbol Ω. The bigger the resistance value (in ohms) the more it fights. Most resistors you'll see range between 1 ohm and 1 megaohm (1.0 MΩ). Since the resistive element is inside a ceramic casing, its not possible to tell the resistance of a resistor just by looking at it. http://lednique.com/current-voltage-relationships/resistance-of-an-led/
