# 1. Product Introduction ## 1.1 Product Safety 1\. This product contain tiny pins, please keep them out of reach of children. 2\. Please operate according to the requirements of tutorials. Improper operation may cause parts to overheat damage. Pay attention to electrical safety. --------------- ## 1.2 Introduction ![Img](./media/AB.jpg) Nowadays, technological education such as VR, kids programming, and artificial intelligence, has become a mainstream in educational industry. Thereby, people attach more importance to STEAM education. Arduino is notably famous for Maker education. So what is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software.Arduino boards are able to read inputs - light on a sensor or a Twitter message - and turn it into an output - activating a motor, turning on an LED,publishing something online. Based on this, Keyestudio team has updated a turtle robot V3.0. It has a Keyestudio 4.0 board compatible with Arduino IDE and Scratch. The 4.0 board can read sensors and controls drivers by a driver expansion board. This product boasts 16 learning projects, from simple to complex, which will guide you to make a smart turtle robot and introduce the detailed knowledge about sensors and modules. --------------- ## 1.3 Kit List **When you receive this kit, check it according to the following list to ensure that all parts are intact.
