Arduino controlled water pump

Projects General Guidance
1

Hey Guys!
I am new to Arduino Programming. I am on a project of a self watering plant. What it does is that when the moisture level is low the water pump(3-6v) supplies water to the plant until the moisture level is high enough. So i developed this code but i am not sure with the programming. I would really appreciate if you guys would be kind enough to correct my mistakes and update it.
This is the code:

int thresholdUp = 600;
int thresholdDown = 450;
int mostureSensor = A0;
int Water_Pump = A3;
int sensorValue = moistureSensor;
void setup() {

pinMode(Water_Pump, OUTPUT);

void loop() {

int sensorValue = analogRead(moistureSensor);
Serial.println(moistureSensor);

if (sensorValue > 800 && sensorValue < 1500)
{

digitalWrite(Water_Pump, HIGH);
else (sensorValue >300 && sensorValue < 600)
{
delay(2000);
digitalWrite(Water_Pump, LOW);
}

}
}

Do suggest me about the threshold values too.

It doesn't compile.

Check for spelling mistakes in your variables.

Where does setup() end?

Do a bit of reading about the else part of how if / else if / else statements work.

You'd have to work out your own threshold values by experimentation.

The maximum value of an analogRead is 1023. I would code it like this:

  if (sensorValue > 800 )
  {
     digitalWrite(Water_Pump, HIGH);
  } 
  else (sensorValue >300  && sensorValue < 600) 
  {
     delay(2000);
     digitalWrite(Water_Pump, LOW); 
  }

When You typr "{" the "}" is issued automaticly but not always placed where You would like it. Whatch out!

Do You know what the plants need? Some need the cycling, getting a bit dry and then getting water. Some other plants might need a relatively stable humidity…… The values 800 and 600 might need different size of difference for various plants. Good luck!
