Thank you PCBWay for supporting this tutorial and helping users learn more about electronics.

NEW! Now you can get Aluminum PCB & FLEX PCB in their Special Offer!

What I like about the PCBWay is that you can get 10 boards for approximately $5 which is really cost effective for professional made boards, not to mention how much time you save!

Go check them out here. They also offer special discounts celebrating their 9th anniversary More info here.

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.

If you power the Arduino module and rotate the rotary encoder sensor the Stepper Motor will start to rotate in forward direction or reversed direction and if you press the button on the rotary encoder sensor the second motor will start to rotate.

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