Ywrobot High Brightness Led Control With Rotary Encoder

In this Visual Programming (Visuino) tutorial, we’ll use the YwRobot High Brightness Lighting LED Module and a Rotary Encoder to control LED brightness and blinking modes.

• Rotate the encoder to smoothly adjust LED brightness from low to high (and vice versa).
• Press the encoder button to toggle between steady glow and blinking mode.
• Brightness can be adjusted in both modes for complete flexibility.

This project shows how simple it is to build interactive lighting effects with Arduino and Visual Programming (Visuino).

Note: you can use any other LED, it will work the same.
