help with multiple inputs to multiple outputs

Using Arduino Project Guidance
1

Hey guys,

This is my first attempt at using the arduino board (UNO).
my goal is to make a water level/control system for my Christmas tree.
It will consist of two tanks one with 5 leds that show the water level and tell when to turn the refill pump on.
The first tank I want as follows:

I want 5 leds to turn on when the water is full.
I want 4 leds to turn on when the water is 75%full.
I want 3 leds to turn on when the water is 50%full.
I want 2 leds to turn on when the water is 25%full.
and I want 1 led and the pump to turn on when the water is at 0%.

The second tank i want as follows:
I want the motor/pump to remain off if water is empty in tank #2 and I want an LED and buzzer to sound.

attached is a copy of my sketch. Like I said I am new to the microcontroller programming so any help would be appreciated.

int ledPinbuzz = 2;
int ledPin0 = 3;
int ledPin25 = 4;
int ledPin50 = 5;
int ledPin75 = 6;
int ledPin100 = 7;
int ledPinref = 8;
int sensePinbuzz =A0;
int sensePin0 =A1;
int sensePin25 =A2;
int sensePin50 =A3;
int sensePin75 =A4;
int sensePin100 =A5;
int motorPin = 9;
int x=850;

void setup() {
analogReference(DEFAULT);

pinMode(ledPinbuzz, OUTPUT);
pinMode(ledPin0, OUTPUT);

pinMode (sensePin50, INPUT);
pinMode (sensePin75, INPUT);
pinMode (sensePin100, INPUT);

int valbuzz = analogRead(sensePinbuzz);
int val0 = analogRead (sensePin0);
int val25 = analogRead (sensePin25);
int val50 = analogRead (sensePin50);
int val75 = analogRead (sensePin75);
int val100 = analogRead (sensePin100);
digitalWrite(ledPinref, HIGH);
Serial.begin(9600);
}

// the loop function runs over and over again forever
void loop() {
int valbuzz = analogRead(sensePinbuzz);
int val0 = analogRead (sensePin0);
int val25 = analogRead (sensePin25);
int val50 = analogRead (sensePin50);
int val75 = analogRead (sensePin75);
int val100 = analogRead (sensePin100);

Serial.println(val0);
delay(1000);

if (valbuzz>x && val0<x && val25<x && val50<x && val75<x && val100<x)
digitalWrite(motorPin,HIGH),(ledPin0 && ledPin25 && ledPin50 && ledPin75 && ledPin100,LOW);

else if (valbuzz>x && val0>x && val25<x && val50<x && val75<x && val100<x)
digitalWrite(ledPin0,HIGH),(motorPin && ledPin25 && ledPin50 && ledPin75 && ledPin100,LOW);

digitalWrite(ledPin0 && ledPin25,HIGH),(motorPin && ledPin50 && ledPin75 && ledPin100,LOW);

digitalWrite(motorPin,HIGH),(ledPin0 && ledPin25 && ledPin50 && ledPin75 && ledPin100,HIGH);

Here is a rough drawing of the basic hook ups

digitalWrite(motorPin,HIGH),(ledPin0 && ledPin25 && ledPin50 && ledPin75 && ledPin100,LOW);

This looks wrong.
You can only set one pin with digitalWrite()
If you want to light ledPin0 you need another digitalWrite(lepPin0, HIGH); etc.

And the correct way to do an IF statement is

if (x >y ) {
 //stuff to do
}

Note the {}

If you have a variable representing the state of each LED which is set in accordance with the analog reading you can eliminate all the complex IF statements. Something like this

led0State = 0;
led1State = 0;
// etc
val0 = analogRead(sensePin0);
// etc
if (val0 > x) {
   led0State = HIGH;
}
if (val1 > x) {
  led1State = HIGH;
}
// etc

digitalWrite(ledPin0, led0State);
// etc

If you store the ledPins, states etc in arrays you can shorten the code even more and avoid repeated typing that may have errors.
