Blink
|
||
Turns on an LED on for one second, then off for one second, repeatedly.
|
||
反复的点亮LED一秒钟，然后关闭LED一秒钟。
|
||
|
||
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
|
||
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
|
||
the correct LED pin independent of which board is used.
|
||
If you want to know what pin the on-board LED is connected to on your Arduino model, check
|
||
the Technical Specs of your board at https://www.arduino.cc/en/Main/Products
|
||
很多Ａｒｄｕｉｎｏ开发板上带有一个你可以控制的ＬＥＤ． 在UNO, MEGA 和 ZERO型号的开发板上，
|
||
这个ＬＥＤ连在了引脚１３上。 在MKR1000型号的开发板上，这个ＬＥＤ连在了引脚６上。无论使用哪
|
||
种型号的开发板，LED_BUILTIN可以代表正确的LED引脚编号。
