Week 1-2    The Arduino C Language

1. Introduction

In this lecture, the fundamentals of the Arduino C language are introduced. The important contents in this lecture are data types, operators, the ‘for’ loop, the ‘while’ loop, the ‘if’ statement, and the ‘switch’ statement’.

2. The Code and the Results

Figure 1: An example of the ‘switch’ statement.

In Figure 1, an example of the ‘switch’ statement is presented. The 'switch' statement works in the following way: the 'switch (i)' line detects the value of 'i' and enters the specific case directly and then run all the rest of the 'cases' below this entry. However, if a ‘break’ statement is added, it will skip all the other statements below.
