In this tutorial, we’ll use OSOYOO V3.0 Servo Steer Sport Car for Arduino to do some simple movements. Once the car installation is completed, it is very important to test the installation and sample code. If you have passed the test movement of this lesson, it means  Arduino MEGA2560, motors, battery, model X board, servo motor and wire connections between these parts are all functioning well, and you can move on other sample lessons

If you don’t complete the frame of car, please review Lesson 1

If you haven’t install PWMservo library, please download and install this Arduino Library from:

1.  Download the file from

2. unzip the file, upload steer-test.ino file to Arduino IDE, you car will move forward  and then move backward  , and turn left     then turn right, then back to right and finally back to left.
