MicroPython不仅能控制输出，还能读取各种传感器的数据。让我们来读取一个模拟传感器的值： from machine import ADC， Pinimport timeadc = ADC(Pin(34)) # 创建ADC对象，连接到GPIO 34while True： value = adc.read() # 读取模拟值 voltage = value /
value(0) p0.value(1) # create an input pin on pin #2, with a pull up resistor p2 = Pin(2, Pin.IN, Pin.PULL_UP) # read and print the pin value print(p2.value()) # reconfigure pin #0 in input mode with a pull down resistor p0.init(p0.IN, p0.PULL_DOWN) # configure...
先上代码: frommachineimportTouchPad,Pin#引入touchpad模块fromtimeimportsleepled=Pin(12,Pin.OUT)#在12脚外接一个led灯,也可利用板子自带ledtouch_pin=TouchPad(Pin(14))#定义14脚为触摸脚whileTrue:touch_value=touch_pin.read()print(touch_value)#打印出14脚感应的值iftouch_value>500:#若读取的值大于阀值...
from machine import Pin p2 = Pin(2, Pin.OUT) # create output pin on GPIO0 p2.on() # set pin to "on" (high) level p2.off() # set pin to "off" (low) level p2.value(1) # set pin to on/high p0 = Pin(0, Pin.IN) # create input pin on GPIO2 print(p0.value()) #...
# 关灯 >>> led.value(1) >>> led.on() # 开灯 >>> led.value(0) >>> led.off()记住，...
