You will see that two other LEDs start to blink. They are called “TX” and “RX”. These two LEDs are the indicators of communication. Every time they blink communication to the Arduino Uno board is going on. Communication happens when you upload a sketch to the board. As soon as the...
首先把电阻的一只引脚连接到 LED_BUILTIN 常量所指定的数字引脚,然后把 LED 灯较长的一只脚与电阻相连,最后把 LED 较短的另一只脚(负极、阴极)接到 GND 地。下图我们展示了 UNO 板的接法,而它 LED_BUILTIN 的常量值为 D13。 连接LED 的电阻阻值可以比 220欧更高,只要低于 1K欧 LED 都能点亮。 原理图...
这里是在昨天的基础之上继续做的实验,只需要将昨晚的 Blink 代码修改一下即可使用。 拷贝一份示例代码 /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin...

打开Arduino IDE后,我们载入项目示例(可以看到这边有很多官方提供的示例代码,可以一个个尝试学习),有英语阅读能力的可以参考[官方文档](https://www.arduino.cc/en/Tutorial/Blink)然后是选择开发板(这边我是UNO)现在将Arduino UNO通过USB线接入电脑(接入之后Arduino UNO开发板上的电源指示灯会长亮,而LED灯...
开发板:Arduino_Uno ▲ 设置端口与开发板信息 (2)测试程序 下面的程序是从“文件”菜单中的“示例程序”中自动生成的“Blink without Delay”。 修改其中的: const long interval=1000 可以修改闪烁LED的频率。单位: ms。 下面是完整的程序。
以UNO上传程序为例子:1.出现Error:Problem uploading to board这个问题多半是由于板子上有一个使用了Serial的程序,由于这个程序会不断向串口传输数据,就会导致无法上传。解决方法有2个:第一,按下板子上的reset键,然后马上按下upload键。这个方法有可能失败,所以要多试几次。第二就是在电脑上上传blink程序,之后再连...
