import utime
LED = Pin(0, Pin.OUT) # 紫色LED，端口0 KEY = Pin(1, Pin.IN) # 按键，端口1，配置成IN模式
while True: if KEY.value()== 0: # 按键按下 #LED每秒闪烁一次 LED.value(1) # LED亮 utime.sleep(1) LED.value(0) # LED灭 utime.sleep(1) else: #LED每0.2秒闪烁一次 LED.value(1) # LED亮 utime.sleep(0.2) LED.value(0) # LED灭 utime.sleep(0.2)
按键使用小技巧：按住Ctrl键然后按下按键后不会弹起。

方法二：
mian.py
这个例子是实现按键操作
from machine import Pin import utime
LED = Pin(0, Pin.OUT) # 紫色LED，端口0 KEY = Pin(1, Pin.IN, Pin.PULL_UP) # 按键，端口1，配置成IN和PULL_UP
while True: if KEY.value()== 0: # 按键按下 #LED每秒闪烁一次 LED.value(1) # LED亮 utime.sleep(1) LED.value(0) # LED灭 utime.sleep(1) else: #LED每0.2秒闪烁一次 LED.value(1) # LED亮 utime.sleep(0.2) LED.value(0) # LED灭 utime.sleep(0.2)
