1. Introduction

www.keyestudio.com
Nowadays, technological education such as VR, kids programming, and
artificial intelligence, has become mainstream in educational industry.
Thereby, people attach importance to STEAM education. Arduino is pretty
notable in 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, a finger on a button, 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 designed a turtle
robot. It has a processor which is programmable using the Arduino IDE, to
mapped its pins to sensors and actuators by a shield that plug in the
processor, it reads sensors and controls the actuators and decides how to
operate.
15 learning projects, from simple to complex, will guide you how to make a
smart turtle robot on you own and introduce the detailed knowledge
about sensors and modules.
Simultaneously, it is the best choice if you intend to obtain a DIY robot for
learning programming, entertainment and competition requirement.
