Serial to Parallel Shifting-Out with a 74HC595 - Arduino
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.
How 74HC595 Shift Register Works & Interface it with Arduino
The solution is to use a ‘shift register,’ which allows you to add more I/O pins to the Arduino (or any microcontroller). By far the most widely used shift register is the 74HC595, also known as just “595”. The 74HC595 controls eight different output pins with only three input pins.
