Problem with reading digital pins.

Well i got a few E18-D80NK infrared sensors ( sensors operates on 5v ).  that trigers low A pulse on detection.
It works fine with an Arduino Uno (sensors work), I adjusted the sketch for the Proto board with a 32U4
And made some text display output instead of led outputs.

But although i can set ports by connecting them to +5v output or ground, its not working with the sensors.
Does the Proto board also require the Indio library.  ? (the website  tells it doesnt).

My sketch roughly looks like below     ( i removed some of our project related parts)

#include <UC1701.h>
static UC1701 lcd;

bool tracked = false;

int Asensor = 4;   // since it didnt work i made this code more flexible so its more easy to change to other ports.
int Bsensor = 6;

void setup()  
{
 // at 9600 baud it takes about 960 bytes p seccond ea 0.001ms p character
 Serial.begin(9600); //Start serial communication boud rate at 9600
 pinMode(Asensor,INPUT); //Pin 4 as signal input sets
 pinMode(Bsensor,INPUT); //Pin 6 as signal input

 lcd.begin();
}

void loop() 

{

// both arrays below are for visual output

String pins [21] ={"00","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20" };
String KnightRider[13] = {
  "                 x",
  "               xx ",
  "             xxx  ",
  "            xxx   ",
  "          xxxx    ",
  "        xxxxx     ",
  "       xxxxx      ",
  "      xxxx        ",
  "    xxxx          ",
  "   xxx            ",
  "  xxx             ",
  " xx               ",
  "x                 ",
};

digitalWrite(13,0);  //turns the light on of the display it seams
int effect =0;
int effectSign = +1;
int dummycounter;
 while(true) 

{
    dummycounter++;
    if (dummycounter%5==0)effect = effect +effectSign;
    {
    if (effect ==12) effectSign=-1;
    if (effect ==0) effectSign = 1;
    lcd.setCursor(0, 2);
    lcd.print(KnightRider[effect]);   // simple effect to show the code is running, not halting or so.
    lcd.setCursor(1, 3);
    String sensA ;
    String sensB  ;
    if (digitalRead(Asensor)==LOW)sensA="Low";else sensA = "High";
    if (digitalRead(Bsensor)==LOW)sensB="Low";else sensB = "High";
    String digstatus ;
    digstatus= "A-Pin("+pins[Asensor]+") = " + sensA +"   " ;
    lcd.setCursor(1, 3);lcd.println(digstatus);
    digstatus = "B-Pin("+pins[Bsensor]+") = " +sensB+ "   ";
    lcd.setCursor(1, 4);lcd.print (digstatus);
    }

  }

}
