2. 照度/噪声计

用掌控板板载的麦克风和光线传感器,可以制作个检测环境的噪声计或者照度计!

from mpython import *

u=UI(oled)
while True:
    oled.fill(0)
    lightValue=numberMap(light.read(),0,4093,0,100)
    soundValue=numberMap(sound.read(),0,4093,0,100)
    u.stripBar(35,8,10,40,soundValue,0)
    u.stripBar(90,8,10,40,lightValue,0)
    oled.DispChar("噪声计",23,50)
    oled.DispChar("照度计",76,50)
    oled.show()
