It is software which finds, downloads and istalls the correct driver for you - automatically.After downloading your driver update, you will need to install it. Driver updates come in a variety of file formats with different file extensions. 
LCD or Liquid Crystal Display is a very important part of many Arduino projects. It can be used to display data received by sensor/sensors connected to Arduino. This video will help you to connect and program LCD with Arduino Uno. What are the required components? The required components are given below. Product description: AVR 2 programmer compatible with USBasp ISP. The programmer 'USBasp AVR' is fully compatible with the programmer 'USBasp' created by Thomas Fischl. It can be used to program microcontrollers from the AVR family from ATMEL via the USB port of the PC.
LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display a few characters in it.
8×8 matrix consists of 64 dots or pixels. There is a LED for each pixel and these LEDs are connected to total of 16 pins. You can identify the pin out and circuit diagram of it using the following figure.
C1 – C8 – Column pins
R1 – R8 – Row pins
As you can see all anodes of same row is connected to one pin and all cathodes of same column are connected to another pin.We have 8 row pins and 8 column pins. If a positive voltage is applied to R1 pin and negative to C1, we can see that the first pixel turns on. If we apply negative to C2 then the second pixel turns on. Like this we can turn each pixel by hanging the supply pins. However we have 64 supply combinations, and doing it manually is practically impossible. This is why Arduino is interfaced with the 8×8 matrix.
Circuit Diagram
As you can see in the diagram every column pin is connected to Arduino pin through a 220Ω resistor. All the row pins are connected to one of the output pin of the shift register. The characters are displayed using the multiplexing techniques. Shift register is connected to Arduino as usual by data, latch and clock pins.

Arduino Code
Code Explanation
In the code all important lines are commented. The digitalWrite command is used for controlling the column pins and shiftOut command is used to write to shift register. Letters are defined in a byte array when the characters displaying 0 are OFF and 1 is ON. This way you can define your own letters or symbols. In the multiplexing method shiftOut(dataPin, clockPin, LSBFIRST, B00000000); line is used to reduce the flicker by turning off all the pixels after each step.
Breadboard Configuration
You can see the actual bread board setup in the following figure.
