Arduino programs can be divided in three main parts: structure , values (variables and

constants), and functions .

一 Structure

setup()

loop()

1.1Control Structures

break

continue

return

goto

1.2Further Syntax

; (semicolon)

{} (curly braces)

// (single line comment)

/* */ (multi-line comment)

#define

/ (division)

% (modulo)

1.4Comparison Operators

== (equal to)

!= (not equal to)

< (less than)

> (greater than)

<= (less than or equal to)

>= (greater than or equal to)

1.5Boolean Operators

2

& reference operator

& (bitwise and)

| (bitwise or)

^ (bitwise xor)

~ (bitwise not)

<< (bitshift left)

1.8 Compound Operators

*= (compound multiplication)

/= (compound division)

&= (compound bitwise and)

|= (compound bitwise or)

setup()

loop()

setup()

The setup() function is called when a sketch starts. Use it to initialize variables, pin

modes, start using libraries, etc. The setup function will only run once, after each

powerup or reset of the Arduino board.

Example

After creating a setup() function, which initializes and sets the initial values, the loop()
