How does the 74hc595 shift register work on an Arduino?
The 74HC595 is a serial-to-parallel shift register or SIPO (Serial In Parallel Out) device for increasing the number of outputs from your microcontroller. Its simply a memory device that sequentially stores each bit of data passed to it. You send it data by presenting a data bit at the data input and supplying a clock signal to the clock input.

How to make a 16 bit shift register?
Making a 16 bit shift register is very simple it is just using a 74HC595 daisy chain. All you do, is to use two 595’s and connect the data output from the first shift register to the data input of the next one i.e. connect the QH’ of the first 595 to the SER (serial data input) of the next.
Is there an extension module for the shift register?
WiringPi supports an extension module for the 74×595 shift register chips which can be used as general purpose output ports.
What kind of shift library does wiring Pi use?
WiringPi includes a simple shift library. This allows you to shift 8-bit data values out of the Pi, or into the Pi from devices such as shift-registers (e.g. 74×595) and so-on, although it can also be used in some bit-banging scenarios. To use, you need to make sure your program includes the following files:
