pico点灯代码：

#电路图上可以看出，led连接的是25号引脚，操作25号引脚即可from machine import Pinimport timeled = Pin(25, Pin.OUT)while True:    led.value(1)    time.sleep(0.5)    led.value(0)    time.sleep(0.5)

pico w 点灯代码：

#电路图上可以看出，led连接的是WL_GPIO引脚，操作此引脚即可，但是在Pin类中，已重定义灯的引脚为“LED”，所以操作LED即可from machine import Pinimport timeled = Pin(25, Pin.OUT)while True:    led.value(1)    time.sleep(0.5)    led.value(0)    time.sleep(0.5)
