Arduino turns LEDs off when set 'high', opposite direction as coded

Question

I've got a function that decreases over time (1000 / 60 seconds) and by touching a softPotentiometer you can increase that value. By every increment of 200 a LED is lid. So for 0-200, 1 LED; 201-400, 2 LEDs; etc. And since it decreases over time while doing nothing, if it drops below a certain value, a LED is shut off.

However, I've got a (amateur) coded set up, but somehow it lids the LEDs in the opposite direction. In a way that, I've coded it that if it's above 800, lid 5 LED's. However, it will only lid one LED when it's dropped below the 800, in the area of 601-800.

That's exactly the opposite of what I want. So what am I doing wrong here?

My code:
And with amateur, I mean that I didn't use arrays and therefor write everything multiple times..

int cleanCount = 1000;
int IsItWorkingLED = 13;
int softpotPin = A0; //analog pin 0
int LED1 = 1;
int LED2 = 2;
int LED3 = 4;
int LED4 = 5;
int LED5 = 7;



void setup () {
    Serial.begin(9600);
    digitalWrite(softpotPin, HIGH); //enable pullup resistor    
        pinMode(1, OUTPUT); 
        pinMode(2, OUTPUT); 
        pinMode(4, OUTPUT); 
        pinMode(5, OUTPUT); 
        pinMode(7, OUTPUT);

           digitalWrite(1, HIGH);   // turn the LED on (HIGH is the voltage level)
           digitalWrite(2, HIGH);   // turn the LED on (HIGH is the voltage level)
           digitalWrite(4, HIGH);   // turn the LED on (HIGH is the voltage level)
           digitalWrite(5, HIGH);   // turn the LED on (HIGH is the voltage level)
           digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)

}


void loop() {
    int softpotReading = analogRead(softpotPin);
    if (softpotReading < 980) { // IF TOUCHED
        digitalWrite(IsItWorkingLED, HIGH); 
        ++cleanCount;
        Serial.println(cleanCount);
        delay(16); // Drain 5 times as fast
    }
    else if (softpotReading > 980) { // IF NOT DTOUCHED
        digitalWrite(IsItWorkingLED, LOW); 
        --cleanCount;
        Serial.println(cleanCount);
        delay(64); // 1000 / 60 seconds
    }
    else {      // Als er een fout optreed..
        Serial.println("Something wrong!");
        digitalWrite(IsItWorkingLED, HIGH);    
        delay(250);               
        digitalWrite(IsItWorkingLED, LOW);

    }

        if (cleanCount >= 0 && cleanCount <= 200) {

Answer 1

If your LEDs are connected anode to +5, cathode to i/o pin, they would behave this way. Cathode to ground, anode to i/o would behave as you expect.

Answer 2

Try reversing the if statements. You say:

I've coded it that if it's above 800, lid 5 LED's.

And your code is: (softpotReading < 980) { // IF TOUCHED

The code describes: IF softpotReading IS SMALLER THAN 980, DO{ code.. }

In dutch (as OP is dutch, and to be honest his English somehow confuses me a bit, to be sure it's not the other way around also):

Ik denk dat je de IF statements verkeerd om hebt. Je beschrijft dat bij een waarde hoger dan 800 de ledjes aan gaan...

Echter staat in je code (softpotReading < 980) { // IF TOUCHED Wat dus zal betekenen dat de code wordt uitgevoerd als die < (kleiner dan) 980 is.

---

    if (softpotReading > 980) { // IF TOUCHED
    digitalWrite(IsItWorkingLED, HIGH); 
    ++cleanCount;
    Serial.println(cleanCount);
    delay(16); // Drain 5 times as fast
}
else if (softpotReading <= 980) { // IF NOT DTOUCHED
    digitalWrite(IsItWorkingLED, LOW); 
    --cleanCount;
    Serial.println(cleanCount);
    delay(64); // 1000 / 60 seconds
