当您打开Arduino IDE时,为了正确设置IDE,请转到:工具》端口》……,然后选择带有Arduino Uno名称的端口。 对于Windows,它应该类似于“ COM4(Arduino/Genuino Uno)”。 对于Linux,它类似于“/dev/ttyACM0(Arduino/Genuino Uno)”。 ,对于操作系统“/dev/cu.usbmodem1461(Arduino/Genuino Uno)”。 然后转到工具...
在Arduino IDE中,点击文件->示例->01 Basics->Blink voidsetup(){// initialize digital pin LED_BUILTIN as an output.pinMode(LED_BUILTIN,OUTPUT);}// the loop function runs over and over again forevervoidloop(){digitalWrite(LED_BUILTIN,HIGH);// turn the LED on (HIGH is the voltage level)...

Arduino Uno的 面包板(和一些面包板电线) 发光二极管(LED)(大多数 LED 都可以工作) 电阻器(220 Ω) Arduino闪烁LED电路 要将LED 连接到 Arduino,您需要一个与 LED 串联的电阻器。这是为了限制 LED 从 Arduino 引脚中拉出的电流。该值并不重要,但应介于 220 Ω和 1000 Ω之间。
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } 让我们试着使用不同的Arduino的引脚-叫做D7。将红色跳线引脚从D13...
