I know that there are many examples on this topic however I wanted to make a simple and compact instructable with five examples:

1)One way shift

2)Two way shift

3)Two way shift with increasing speed

4)Random LED

5)Random Fill

Supplies

Arduino Uno (original or any clone), male-male jumper cables, 8 LEDs, 8 33o Ohm Resistors, Breadboard, Arduino IDE

The connections:

-All LEDs through 330 Ohm resistors and to 8 output pins of the 74HC595 shift register

-Shift Register Vcc pin to Vcc of Arduino

-Shift Register GND pin to GND pin of Arduino

-SRCLR active low output to Vcc

-OE active low output to GND

-SER input of Shift Register to Pin 12 of Arduino

-RCLK pin of the Shift Register to Pin 10 of Arduino

-SRCLK pin of the Shift Register to Pin 11 of Arduino

Use the following code to shift in one way:

Use the following code to shift back and forth:

Use the following code to shift back and forth with increasing speed:

Use the following code to make a random LED on:

Use the following code to fill all LEDs randomly:
