2. read multi-channel sensor value with arduino

   

    int En0 =7; //Lowenabled
    int En1 =6; //Lowenabled
    int S0  =5;
    int S1  =4;
    int S2  =3;
    int S3  =2;
   
    int SIG_pin=A3;
   
    int readMux(int channel){
        int controlPin[]={S0,S1,S2,S3,En0,En1};
        int muxChannel[32][6]={
            {0,0,0,0,0,1},//channel0
