1、ARDUINO 编程语法基础结构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);控制结构ifif.elseforswitch casewhiled
