Why is my breadboard not connecting to my arduino????!!!! I have been trying to do this project for the past month and it hasen't worked at all. I have used new LEDs, new resistors, wires and it still has not worked Can someone plz help me out here 
I recommend starting with Lesson 0 on the Adafruit site and work your way through the lessons. It will take you through hooking up a breadboard with various things like LEDs and resistors.
In a case like this, a volt meter is your number one tool. Check the voltage at each point. If you have a bad connection, you will not read the voltage that you expect.

Show us a photo of your setup.
Maybe your code too, but please make sure it's between code tags. </> at the upper-left of the post window.
Yes, like OldSteve, I suspect that you are not hooking the wires into the right holes. Use a phone, and take a close-up of how you are connecting the Arduino to the breadboard

Oh, please don't!
Use a proper camera, and take a perfectly focussed photo - in daylight outside but not in the direct sun - from more than a metre away using zoom to home in on the complete assembly. Useless if not focussed.
Still hasen't worked
So we see.
Assumption:
The way you have it wired isn't the same as shown in your schematic.

This is very informative. Thank you for providing us with so much information, it makes it really easy to help you.
And thank you for providing a clear photo, along with your code and schematic as asked. Without all of this valuable info, we would have been totally lost and unable to help you.
Do you know how a breadboard works?
Step 1 is to understand how a breadboard works:
Step 2 is to use a simple blink example:
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Step 3 try to experiment with your own simple projects
Add more leds, buttons, switches.
Good luck

Actually, he did ask a question:-
Why is my breadboard not connecting to my arduino?
This is pretty funny. I gave a recommendation in November. Perhaps that also didn't work. Maybe nothing will work.
Maybe the breadboard battery is dead!
maybe..... or the breadbord detector on the arduino....

I dunno. Why don't you have a close look at it with your new eyeball!

Yep, that was the problem:
Damn that's funny. We are quite a team solving the OP's problem with very little info.

A lot of first post questions are answered at length, but then the OP never returns. A lot of them have follow-up questions that are never answered by the OP. Occasionally a noob engages in conversation but that is a minority of threads started by first time posters. I believe the reason is that expectations here is that the forum is run by the "company", Arduino, and that providing quick, correct and authoritative answers is part of the purchase price.
Of course none of that is true - the members here are independent of "Arduino", and provide their opinions (which in many cases are very well informed) on any particular question. It is then up to the questioner to figure out what to do. In many cases, they leave, just as confused as they come. As far as I can tell, mst of the folks here with more than a thousand posts are pretty knowledgable about things Arduino. Often newbs pay no attention to things like karma or number of posts, and listen for what they want to hear.
I believe this is one of those cases. The OP is unlikely to return, and is not reading the posts here. Wasted time? -Nope. 1) others passing through learn about the culture here, and 2) we are entertained. It's all good.
ps, Paul_B: it's the lighting, set-up and most of all, the photographer, not the camera! Cell phone cameras have come a long way in the last few years. For example:
