Patterns in cascaded 16-bit serial-in parallel-out shift register modules using Arduino UNO
/* Shift Register Example Turning on the outputs of a 74HC595 using an array Hardware: * 74HC595 shift register * LEDs attached to each of the outputs of the shift register */ //Pin connected to ST_CP (12) of 74HC595 int latchPin = 12; //Pin connected to SH_CP (11) of 74HC595 int clockPin = 11; ////Pin connected to DS (14) of 74HC595 int dataPin = 10; //holders for information you're going to pass to shifting function byte data;
