Want to control those fancy 7-segment LEDs but tight on i/o pins? Why not use the 74HC595 serial in/parallel out 8-bit shift register! This tutorial shows you the basic principles of how the useful IC works, and some example code that includes cycling through the digits of a 7-seg LED display, as well as your very own voltmeter (0-5v, rounds to the nearest volt)!
