Control Servo Motor Using ATOM Matrix ESP32 & Visuino

Step 1: What You Will Need

• ATOM Matrix ESP32
• Jumper wires
• Servo motor
• Visuino program: Download Visuino

Step 2: The Circuit

• Connect Servo pin [VCC] to Atom Matrix pin [5V]
• Connect Servo pin [GND] to Atom Matrix pin [GND]
• Connect Servo pin [Signal] to Atom Matrix pin [G25]

Step 3: Start Visuino, and Select the Atom Matrix 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 "Atom Matrix" as shown on Picture 2

Step 4: In Visuino Add Components

• Add "Counter" component
• Add "Integer To Analog" component
• Add "Servo" component

Step 5: In Visuino Set Components

• Select "Counter1" and in the properties window set "Max">"Value" to 10
• Select "IntegerToAnalog1" and in the properties window set "Scale" to 0.1

Step 6: In Visuino Connect Components

• Connect "M5 Stack ATOM Matrix" > "Button" pin [Out] to "Counter1" pin [In]
• Connect "Counter1" pin [Out] to "IntegerToAnalog1"pin [In]
• Connect "IntegerToAnalog1" pin [Out] to "Servo1" pin [In]
• Connect "Servo1" pin [Out] to "M5 Stack ATOM Matrix" pin [GPIO 25]

Step 7: Generate, Compile, and Upload the Arduino Code

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 8: Play

If you power the ATOM Matrix module and press the Atom button the servo motor will start to rotate.

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