blink_led 程序使引脚 13 闪烁。Arduino 上的引脚 13 不是 AVR ATMEGA8-16PU/ATMEGA168-16PU 引脚 13。它实际上是 ATmega 芯片上的引脚 19。 最后,添加 LED。长腿或阳极连接到红线,短腿或阴极连接到接地的 220 欧姆电阻。 将草图上传到您的 Arduino 你可以去这里了解将草图上传到arduino的方法。 您将需要一个...
Tinkercad supports a curated set ofArduino boards(Uno, Mega, Nano) and components, prioritizing ease over complexity. It’s not built for advanced microcontrollers or low-level debugging, but its real-time simulation—watching LEDs pulse as your code runs—is instant gratification. Think of it a...
您将创建此Blink草图,我们将遍历下面的每一行。 首先定义板载LED引脚。如果您使用的板上板载LED不使用引脚13,请相应地对其进行更改: #define onboard 13 使用您的设置功能来设置引脚模式。/p》 pinMode(onboard,OUTPUT); 请注意VS Code将如何向您建议代码,并在按 Enter 键时完成它! 最后,通过将引脚 HIGH 和 ...

After a second, you should see some LEDs flashing on your Arduino, followed by the message "Done Uploading" in the status bar of the Blink sketch. If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino!

There are three LEDs on the Arduino Nano ESP32 board. The power LED is a green LED mounted beside the USB-C connector. On the other side of the USB-C connector is an amber LED. This is the LED attached to data pin D13, a feature common to most Arduino boards. ...
If the green power LED is on but the pin 13 LED is not flashing, it could be that the factory code is not on the chip; follow the instructions in Recipe 1.3 to load the Blink sketch onto the board to verify that the board is working. If you are not using a standard board, it ...
