ARDUINO 编程语法基础课件

1、ARDUINO 编程语法基础,1,PPT学习交流,结构,setup() loop(),当项目开始运行时会调用setup()函数 常我们在其中初始化一些变量、引脚状态及一些调用的库等 loop函数是一个循环体，其中的程序将会不断的运行,示例 int buttonPin = 3; void setup() Serial.begin(9600); pinMode(buttonPin, INPUT); void loop() if (digitalRead(buttonPin) = HIGH) serialWrite(H); else serialWrite(L); delay(1000); ,2,P
