Rotary Encoder with Arduino

In this video we will go over how to use a Rotary Encoder (KY-040) with Arduino. We’ll focus on basics, module pins, how to connect to Arduino, programming in Arduino IDE, testing, and examples.

*Note that the LED flash used in this example is a ready-to-use component with a built-in resistor, which is why a separate resistor is not needed.
