板子上并没有焊接LED灯,只留出了接口,可以根据自己的需要,按照板子上标出的极性,直接插上LED即可。Led的引脚一般是长正短负,如果引脚被剪过,灯帽上有缺口的为负极,插反LED不会点亮,也不会烧坏。
结构尺寸:

可用端口: A0、A1、A2、A3、S0、S1、S2、S3
示例代码
以S0口为例Arduino IDE下的代码:
/*
Nova_Led
Turns on an LED on for one second, then off for one second, repeatedly.

#include <Nova.h>
LED led = LED(S0); // A0、A1、A2、A3、S0、S1、S2、S3
void setup()
{
}
void loop()
{
// turn the LED on
led.on();
// wait for a second
delay(1000);
// turn the LED off
led.off();
// wait for a second
delay(1000);
}
