Discover an easy way to add more GPIO pins to your Arduino with the PCF8574 in this tutorial. We'll explore how it can be a handy alternative to other methods like shift registers, Max7219, and multiplexing. The video shows you how to control a single LED and a 7-segment display using the PCF8574, making it suitable for various projects. Plus, learn how to use expander pins for input and make the most of the interrupt pin. This tutorial is perfect for both beginners and those with some experience. Hope you find it helpful!

Hi Mario, as always another interesting tutorial...you have gained another sub 👍
I really wanted to try this out, however you didn't include any links to your code.
Look forwards to the next tutorial.

GREAT work! We'd like to offer you some boards if you need them in the upcoming content. (PCBWay Daisy) :D

Let me know what products do you have. I am already talking to PCBWay in terms of using the custom PCB. I will be releasing the first video in a matter of days where I would be giving the shoutout To PCBway for providing me with the printed circuit board. It was supposed to be ready in Jan, but I was busy at worked and had to slow down.
