Dim the RGB LED Arduino Nano ESP32 Using Visuino

Step 1: What You Will Need

• Arduino Nano ESP32
• Visuino program: Download Visuino

Step 2: Start Visuino, and Select the Arduino Nano ESP32 Board Type

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

Step 3: In Visuino Add & Connect Components

• 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"

Step 4: Generate, Compile, and Upload the Project

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.

Step 5: Play

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