ARDUINO编程语法基础市公开课金奖市赛课一等奖课件

1、ARDUINO 编程语法基础第1页结构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库等loop函数是一个循环体，其中程序将会不停运行 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); 第2页控制结构ifif.elsefors
