本文介绍了如何使用掌控板和Blynk实现远程声音和光线检测。首先配置WiFi连接，然后设置Blynk授权码。通过Blynk虚拟引脚读取声音和光线值，并将数据发送到Blynk服务器。最终实现远程监控，适用于青少年科创比赛和STEM教育场景。

[mw_shl_code=python,true]import network,BlynkLib,time,musicfrom mpython import *
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
if not wlan.isconnected():
  print('connecting to network...')
  wlan.connect('Maker Space', '20140811') #wifi信息
  while not wlan.isconnected():
pass
print('network config:', wlan.ifconfig())#输出wifi连接信息
BLYNK_AUTH = 'bf0c2b95ede846c5bbb79fb3bb52b1a7'#Blynk授权码
blynk = BlynkLib.Blynk(BLYNK_AUTH)# 初始化Blynk连接
@blynk.VIRTUAL_READ(0)#声音值
def v0_read_handler():
blynk.virtual_write(0, sound.read())#发送声音值到V0

@blynk.VIRTUAL_READ(1)#光线值
def v1_read_handler():
blynk.virtual_write(1, light.read())#发送光线值到V1
while True:
      blynk.run()#一直运行blynk
      pass
