Webb10 aug. 2024 · 首先我查了下开发板配套的图，发现LED灯是连接在GPIO2端口的，因此只需要控制GPIO2输出高低电平即可控制LED灯的亮灭。自带的例程中，其使用了digitalWrite (LED_BUILTIN, HIGH)和digitalWrite (LED_BUILTIN, LOW)来控制灯亮和灭。我尝试找了下LED_BUILTIN的定义，发现没有找到。后面在Arduino的界面中，发现了一个可以配置 … WebbCreate a new single-byte constant, and name it “led_gpio.”. The LED is connected to GPIO32, so store the value “32” in “led_gpio.”. Then, replace all occurrences of the LED_BUILTIN reference with “led_gpio.”.

WebbIn dit voorbeeld stellen we via de pinMode functie, de LED_BUILTIN in als OUTPUT. Voor de Arduino UNO is LED_BUILTIN gelijk aan pin 13 (de ingebouwde LED). Je zou LED_BUILTIN dus kunnen verangen door 13. Het voordeel van LED_BUILTIN is dat het voor alle Arduino's werkt. Ook als de LED niet op pin 13 zit. De loop() functie Webb如果该引脚通过pinMode()设置为输出模式（OUTPUT），您可以通过digitalWrite()语句将该引脚设置为HIGH（5伏特）或LOW（0伏特/GND ... 在此示例中，当引脚13输出高电平时，引脚13旁的LED（如下照片红圈所示）将被点亮。
