Driver Arduino Uno R3
How to download and install the Arduino software and then install drivers on Windows 7 for the Arduino Uno.

If you have a need to re-flash the ATmega16U2 chip with the stock firmware to restore the Arduino UNO back to normal, this is often done on the command line using avrdude or dfu-programmer, or with the Windows program Flip. The easier way for me is to just use the Arduino IDE. Note: if you are reading this Instructable because your board is in an unknown state, before proceeding you should determine if your ATmega16U2 really needs the firmware restored. Do the loop back test: If the loop back test works, your ATmega16U2 is probably fine, and if you're having trouble uploading to your board it could be the main processor on your board (ATmega328P) needs to be bootloaded. So you need to find a different procedure for bootloading the main processor, perhaps.
The avrdude command is used when you have an ISP programmer or are using another Arduino as an ISP programmer. You connect the programmer to the ICSP header of the ATmega16U2 and upload the firmware. The command is long and tedious, and I need to keep notes about the command somewhere and copy and paste it to the command line. It is so long that I usually split it up into separate lines. This method does not require using the command line and does not require DFU programming. It does require an understanding of how the IDE 3rd party customizations work, and an understanding of where the Arduino documents and Arduino IDE program files are on your computer. In your documents directory and Arduino subdirectory, you have the ability to create a hardware directory structure that includes a boards.txt file and any supporting files such as bootloaders and cores.
The directory structure and file specification for custom boards.txt, bootloader directory, and other add-ons in the Arduino sketches directory is detailed in the Arduino IDE 1.5 3rd party Hardware specification page here: It is worth taking the time to read and understand. Location of custom boards.txt file I have created a directory structure in my documents/Arduino subdirectory called hardware/custom/avr and that is where I keep my custom configurations. The full path on my Mac computer is /Users/david/Documents/Arduino/hardware/custom/avr On my Windows computer it is C: Documents and Settings David My Documents Arduino hardware custom avr On my Linux computer it is /home/David/Arduino/hardware/custom/avr Find your Arduino document or sketch directory on your computer and create the hardware/custom/avr subdirectories. Files in that directory supplement the built-in hardware files that are in the Arduino application's directory structure. This is where you can put a boards.txt file which contains custom board definitions to add to the Arduino IDE menu. Location of custom bootloaders directory Also, create a bootloaders subdirectory in the avr directory.
This is where we will place a copy of the firmware.
