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.
STEP 1
What You Will Need
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
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
STEP 5
Play
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
