Setup humidity sensor

Using Arduino Sensors
1

I'm doing a project with arduino and i don´t know exactly how i can do the setup, if someone give me some help i´ll be thankful

this is my code for now

void loop () (
humiditysensor = analogread(0);
//Serial.println(humiditysensor);
if(((humiditysensor <"minimumvalue")||(humiditysensor>"maximumvalue")) && (x==0 ))
(
for(i=0;i<=11;i++)
(
for(k=0;k<=11;k++)
(
valve=0;
)
)
'x=1;
)
delay(3000);

if(((humiditysensor > "maximumvalue")||( humiditysensor < "minimumvalue")) && (x==1))
(
for(i=0;i<=11;i++)
(
for(k=0;k<=11;k++)
(
valve=1;
)
)
x=0;
)

delay(3000);

)

my ideia is:Sensor read a value and a valve opens or closes
Ps:this is my first project

byte i;
byte k;
byte x;
byte valve;
int humidity sensor;
int minimumvalue = 200; // as needed
int maximumvalue = 800; // as needed

void setup(){
Serial.begin(9600);
}

change this line to:
if(((humiditysensor > maximumvalue)||( humiditysensor < minimumvalue)) && (x==1))
