This is very simple library for Wiring/Arduino interfacing 74HC595 class chip. The chip is connected to 3 pins of Arduino. These are:

• clockPin -- which is connected to pin 11 (SRCLK) of the chip
• dataPin -- which is connected to pin 14 (SER) of the chip
• latchPin -- which is connected to pin 12 (RCLK) of the chip

The interface cant talk only to one HC595 chip. Remember, this is first, quick, version of the library.
