-  Shift Register Example
- for 74HC595 shift register
-
- This sketch turns reads serial input and uses it to set the pins
- of a 74HC595 shift register.
-
- Hardware:
- * 74HC595 shift register attached to pins 8, 12, and 11 of the Arduino,
- as detailed below.
- * LEDs attached to each of the outputs of the shift register
-
- Created 22 May 2009
- Created 23 Mar 2010
