Intro: Arduino 4 Led Madness

 In this instructables you will learn how to wire 4 LED'S and make them flash 10 times. This is a great Starter project!!

what you will need...
1: arduino (I am using an Duemilanove)
1: breadboard
4: LED's
10-15: jumper wires
3: resistors

Step 1: Adding the LED's and Resistors1

 First put the LED's on the breadboard.
Make Sure the long lead is to the left as seen i the picture!
Next add the Resistors to the last 3 LED's,
place in the long lead.

Step 2: Wiring This to the Arduino!

 First the ground, wire 2 grounds to the breadboard like in the picture.
Next going to each led, take 4 more led's and go from the 2 grounds to each short lead.

Step 3: Wiring the Positive Leads!

 For this code you will be using pins 13,12,11,10
pin 13 has a built in resistor so that is why you don't need to use a resistor.
start with pin 13 and wire it to the first LED.
Then Just go do the line and wire the rest of the LED's using pins 12,11,10

Step 4: The Code!!

 There's the code that u need to program your arduino with.

congratulations you did it!!!!!!!!!!!

    Nice little instructable. Would like to see a video of it in action. Then people can know what to expect when they try and build it.

    Oh, and it should be "Congratulations you did it !!!!!!!"  :-)
