2020-01-01 11:03
一、hello world(串口通信)
1、Mixly编程
2、Arduino IDE编程
void setup() {// put your setup code here, to run once:Serial.begin(9600); //初始化串口并设置波特率为9600}void loop() {// put your main code here, to run repeatedly:Serial.println("Hello World!"); //打印Hello World!并回车换行delay(1000); //延时等待1s}
二、UNO板Led闪烁(13号管脚)
1、Mixly编程
2、Arduino IDE编程
void setup() {pinMode(led, OUTPUT); //将"led"引脚设置为输出状态}void loop() {digitalWrite(13, HIGH); //引脚输出高电平1,点亮LEDdelay(1000); //等待1sdigitalWrite(13, LOW); //引脚输出低电平0,熄灭LEDdelay(1000); //等待1s}声明:本文章由网友投稿作为教育分享用途,如有侵权原作者可通过邮件及时和我们联系删除:freemanzk@qq.com
