- At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers.
- This example is based on the 74HC595.
- The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state."
- In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller.
- You can link multiple registers together to extend your output even more.
