Cascading two 32-bit shift register modules using Arduino UNO

Cascading will help you to create multiple outputs. Similarly, you can cascade more modules.

Purchase the module from https://haberocean.com/product/32-bit-serial-in-parallel-out-shift-register-module-using-74hc595/

Upload the following program to Arduino UNO. Change the value in customDelay() function to change the speed of running LED.

/* 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;

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.
