multiple leds

Projects Programming
1

I have been doing a multiple led project (from a starter kit) and it would not work I have pulled out the wires and redid the led placement again and again and I have used many different codes but the leds still would not light up but what is weird is that when I made an led blink it worked and my on and l lights are on when I did my multiple led placement again and again. Is my arduino broken? Here is the error message that comes up when I upload the code: Arduino: 1.5.8 (Windows 8), Board: "Arduino Uno"

Build options changed, rebuilding all

Sketch uses 1,252 bytes (3%) of program storage space. Maximum is 32,256 bytes.

Global variables use 33 bytes (1%) of dynamic memory, leaving 2,015 bytes for local variables. Maximum is 2,048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

Plz help

Is my arduino broken?

Not if other sketches work.

Having LEDs on pins 0 and 1 IS going to cause problems with uploading sketches.

I don''t have anything on pins 0 and 1

You have failed to select the correct Serial port from the Tools menu.

What do you mean by select serial port in tools menu the port tab won't let me click it

Before you can upload anything you have to select the port the arduino is connected to in the tools menu of the IDE. If you can't see the arduino in this menu it means either the arduino is broken or the IDE installation is bad.
Have you ever downloaded any program in the past?

yes, many

The actual code you upload to an Arduino is totally irrelevant to the process of uploading. If you have loaded code before and now your PC is not seeing the Arduino then something is broken. It could be the USB cable or the Arduino or the PC installation of the IDE.

but my on and L led is on

So what has that got to do with anything? LEDs can be on with a broken Arduino, in fact it is difficult for them not to be on with up to 98% of the Arduino broken.
