Wire up an LED

“

- [Narrator] All right, so in this example, we are going to generate pulse width modulation from Arduino to brighten an LED and to dim it. So I'm going to go ahead and start wiring. So it's a very simple circuit, here is a resistor, that's a 33 ohms resistor. And then I'm going to connect the LED to one side of the resistor. So the long side of the LED is going to the side of the resistor. Now the other side of the LED is going to be connected to ground from the Arduino. And the other side of the resistor is going to be connected to pin number nine from the Arduino. And the reason why we selected pin number nine, because it has the tilde sign beside it to generate a pulse with modulation, okay? And the last thing is just connecting the Arduino to the computer.
