这里测试nodemcu板载led

其引脚编号为16

from machine import Pin
p0 = Pin(16, Pin.OUT)    # create output pin on GPIO0
p0.off()                # set pin to "off" (low) level

在交互窗口中输入上诉程序，即可点亮板载led

闪烁

from machine import Pin
import time
p0 = Pin(16, Pin.OUT)    # create output pin on GPIO0
while(1):
    p0.off()                # set pin to "off" (low) level
    time.sleep(1)
    p0.on()                # set pin to "off" (low) level
    time.sleep(1)
