STEP 1

What You Will Need

Arduino Nano ESP32Visuino 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 "Pulse Generator" componentConnect "PulseGenerator1" pin [Out] to Arduino Nano ESP32 > Digital pin [13]If you want to increase the speed of the blinking select "PulseGenerator1" and in the properties window change the "Frequency" value

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 board the internal LED will blink.

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
