3 Pins Controlling 14 (Shift Registers)

Sorry I haven’t been posting in the last few weeks, I’ve been pretty busy with school / swimming.

The Youtube video demonstrating the final product.

Anyways! I’ve set aside my home automation project and picked up a few of these shift registers: the 74hc595 by TI, seen here:

As seen in the video above, I’m controlling 14 led’s using two of the 74hc595s and and 3 pins on an Arduino Uno.

The Breadboard

The program uses a for loop and cycles through the 14 pins on the registers. That code can be found here. Thanks for reading, check back soon for updates on the home automation project.
