0. Hello World
Generally, teacher will teach us to write a simple Hello World example when start to learn a programming language. This only a basic introductory，but it is a very important process. Although you are not familiar about Arduino, do not worry. You can learn the hello world about Arduino: light up a LED. Now we take keyestudio UNO R3 Board as an example to learn how to light up a LED which is controlled by Digital 13 Pin. Before doing this, please make sure that you have downloaded the Arduino Environment and installed the keyestudio UNO R3 Driver successfully.
1. Connect keyestudio UNO R3 Board to PC
