On the Uno boards, there`s an IC which is responsible as a USB to serial converter and it makes it possible to program the Arduino and also communicate with it from the computer. The problem here is the IC is an SMD (Surface Mounted Device). The R3 uses an ATmega 16U2 while the older revisions uses the 8U2. Installation is pretty easy.

Just download the driver from Cytron`s website and execute the installer. Here`s what you`ll see in the device manager after installation. There are many schematics available online for constructing an Arduino on a breadboard, but after an extensive research and some personal modifications, I`ve come up with this.
