Imagine you build a project and then you just run out the pins. You need more pins for your project to drive something.
In this video, we will learn to add more pins to our Arduino board using this module. I will demonstrate it with Arduino UNO and an EPS8266 board WEMOS. We also test the output by blinking LEDs and a relay then test the input of this expander module by reading input from a button and an infrared sensor. And we also try to use more than one module to a single Arduino board so we got 16 additional pins.
