arduino处理流程控制的函数
英文版
Arduino Process Control Functions
Arduino is an open-source physical computing platform
based on a simple I/O board and a development environment
that implements the processing language. It can be used to
develop stand-alone interactive objects or can be connected to
software on your computer (e.g., Flash, Processing, etc.). The
board can be interacted with via various sensors and can control
various devices such as LEDs, motors, servos, and other physical
outputs.
One of the key features of Arduino is its ability to handle
process control functions. These functions allow you to control
the flow of your program based on specific conditions or events.
Here are some of the common process control functions used in
Arduino:
setup(): This function is called once when the Arduino board
resets or powers up. It's typically used to initialize variables, pin
modes, and set up any required hardware components.
loop(): This function contains the main program code that
runs repeatedly in a loop forever. It's where you'll put most of
your program's logic.
if Statements: These statements allow you to check if a
condition is true or false and execute a block of code
accordingly. For example, you can use an if statement to check
if a sensor value is above a certain threshold and turn on an LED
if it is.
else and else if Statements: These statements allow you to
specify multiple conditions and execute different blocks of code
based on which condition is true.
for Loops: These loops allow you to iterate over a range of
values and perform a specific task for each value. For example,
you can use a for loop to blink an LED a specific number of
times.
while Loops: These loops allow you to repeatedly execute a
block of code while a condition is true. They're useful for tasks
that need to continuously run until a specific event occurs.
delay() and delayMicroseconds(): These functions pause the
execution of your program for a specified number of
milliseconds or microseconds, respectively. They're useful for
creating timed delays between actions.
By combining these process control functions, you can
create complex and interactive Arduino projects that respond to
various inputs and control various outputs based on specific
conditions or events.

Arduino处理流程控制的函数
Arduino是一个基于简单I/O板和实现处理语言的开发环境的开
源物理计算平台。它可以用来开发独立的交互式对象，也可以与计算
机上的软件（如Flash、Processing等）相连。该板可以通过各种传
感器进行交互，并可以控制LED、电机、伺服电机等各种设备。
Arduino的关键特性之一是它能够处理流程控制函数。这些函数允
许您根据特定条件或事件控制程序的流程。以下是Arduino中常用的
一些流程控制函数：
setup()：当Arduino板重置或上电时，此函数只调用一次。它通
常用于初始化变量、引脚模式和设置任何所需的硬件组件。
loop()：此函数包含在主程序中不断循环运行的代码。这是您将大
部分程序逻辑放在其中的地方。
if语句：这些语句允许您检查条件是真还是假，并相应地执行一段
代码。例如，您可以使用if语句检查传感器值是否超过某个阈值，并
在超过时打开LED。
else和else if语句：这些语句允许您指定多个条件，并根据哪个
条件为真来执行不同的代码块。
for循环：这些循环允许您迭代一系列值，并对每个值执行特定任
务。例如，您可以使用for循环使LED闪烁特定次数。
while循环：这些循环允许您在条件为真时重复执行一段代码块。
它们对于需要连续运行直到发生特定事件的任务很有用。
delay()和delayMicroseconds()：这些函数分别使您的程序暂停
指定的毫秒数或微秒数。它们对于在动作之间创建定时延迟很有用。
通过结合这些流程控制函数，您可以创建复杂且交互式的Arduino
项目，这些项目可以根据特定条件或事件对各种输入做出响应，并控
制各种输出。
