How to Control a 360 Continuous Servo Motor Using Arduino

In this tutorial we are going to learn how to control the speed and direction of a Continuous Rotation Servo using a potentiometer, button & Arduino.

Watch the video!

Also check outthis great Video on How Continuous Rotation Servo Works

Step 1: What You Will Need

• Arduino UNO (Or any other Arduino)
• 360 Continuous Rotation SERVO Motor
• Potentiometer module
• 1k ohm Resistor
• Jumper wires
• Breadboard
• Visuino program: Download Visuino

Step 2: Brought by PCBWay

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

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 a lot of other stuff in case you might need it like assembly, 3D printing, CNC machining and a lot more.

Step 3: The Circuit

Step 4: Start Visuino, and Select the Arduino UNO Board Type

The Visuino: https://www.visuino.eu also needs to be installed. Download Free version or register for a Free Trial.

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 UNO” as shown on Picture 2

Step 5: In Visuino Add Components

• Add “Debounce Button” component
• Add “Toggle(T) Flip-Flop” component
• Add “Speed and Direction To Speed” component
• Add “Servo” component

Step 6: In Visuino Connect Components

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.
