32-bit shift register module using 74HC595 controlled using Arduino UNO

32-bit shift register module using 74HC595 controlled using Arduino UNO

Here, we will see the circuit to interface a 32-bit serial-in parallel-out Shift register module using Arduino UNO. Shift register module is powered from Arduino UNO.

This module will help to create 32 digital outputs from only 3 digital pins of Arduino. Purchase the module from https://haberocean.com/product/32-bit-serial-in-parallel-out-shift-register-module-using-74hc595/. This module can be used in applications where more digital outputs are required such as LED cube, LED matrix etc.

Upload the following program to Arduino UNO.
