Dim the RGB LED Arduino Nano ESP32 Using Visuino

In this tutorial we will use the built-in RGB LED on Arduino Nano ESP32 and Visuino to make dim the LED using the Pulse Width Modulation (PWM) and Sine Analog Generator component.

Watch a demonstration video.

• Arduino Nano ESP32
• Visuino program: Download Visuino

Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino Nano ESP32" as shown on Picture 2

• Add "Sine Analog Generator" component
• Connect "SineAnalogGenerator1" pin [Out] to Arduino Nano ESP32 > RGB > Blue pin [Digital]

• If you want to change the speed just select the "SineAnalogGenerator1" and in the properties window change the "Frequency"

• In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

After uploading the project to the Arduino Nano ESP32 the internal RGB LED will start to Dim.

Congratulations! You have completed your LED project with Visuino. Also attached is the Visuino project, that I created for this Tutorial. You can download and open it in Visuino: https://www.visuino.com
