1、在智能公元网站上创建产品，设置输出控制信号以及语言控制命令等，并下载了SDK

2、学习树莓派的使用，利用Python编写了声音传感器的控制程序，并利用其和树莓派检测是否有声音
 <nowiki>
import PCF8591 as ADC
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
def msetup():
    ADC.setup(0x48)
def loop():
    count=0;
    while True:
        voiceValue=ADC.read(0)
        if voiceValue:
            print("Sound Value:",voiceValue)
            if voiceValue<80:
                print("Voice detected!",count)
                count+=1
            time.sleep(0.2)
if __name__=='__main__':
    try:
        msetup()
        loop()
    except KeyboardInterrupt:
        pass

3、将下载的SDK烧录到硬件上，并编写新的控制程序完成语音控制，并尝试在程序中加入了对蜂鸣器的控制
