Touchscreen with leds

Leds with Soft Potentiometer Circuit Design

This circuit is designed for switching leds by values that come from soft potentiometer.
Values are mapped according to the number of leds.
Code are shown in below :

/*soft potentiometer with leds*/
const int SENSOR_PIN = 0;
 byte ledPins [7];


void setup()
{
  int i;
  Serial.begin(9600);
  for (i=0;i<7;i++){
    ledPins[i] = i+2;
    pinMode(ledPins[i],OUTPUT);
  }
}
void loop(){
  int sensorValue ;
  sensorValue = analogRead(SENSOR_PIN);
  Serial.print("Sensor Value ");
  Serial.println(sensorValue);
  int openPin = map(sensorValue,0,1023,-1,7);
  Serial.print("pin is ");
  Serial.println(openPin);
  int i;
  for(i=0;i<7;i++){
    if(i == openPin){
      digitalWrite(ledPins[i],HIGH);
    }else{
      digitalWrite(ledPins[i],LOW);
  }
  }
}
