what's the problem with the gray squares at the pins of PORTB, C, D, E that's my project please help me it's urgent
:cry: :cry: :cry:

Code:
void main(){
unsigned int v0,v1,v2,v3,v5;
ADC_Init();  // Initialize ADC module with default set
//CMCON = 0x07; // Disable comparators
ADCON0 = 0x00; // Select ADC channel AN0
ADCON1 = 0x0F; // RA0 as analog input
TRISC = 0x00;
PORTC= 0 ;
PORTA= 0xFF ;
TRISA = 0xFF;
 PORTB= 0 ;
TRISB = 0x00;
 PORTE= 0 ;
TRISE = 0x00;
  PORTD= 0 ;
TRISD = 0x00;

INTCON = 0  ;

  do {

   ADCON0=0b11000101;     // Configure chanal 0

     delay_us(500);
   v0 = ADC_Read(0);   // Get 10-bit results of AD conversion
    delay_us(500);

    ADCON0=0b11001101;     // Configure chanal 1
       delay_us(500);
    v1 = ADC_Read(1);   // Get 10-bit results of AD conversion

    delay_us(500);

    ADCON0=0b11100101;      // Configure chanal 4
      delay_us(500);
    v5 = ADC_Read(5);   // Get 10-bit results of AD conversion
      delay_us(500);
    if ((v0>v5)||(v1>v5));
       {if (v0>v1)                       //  comparaison  des tensions  des capteurs LDR1 et LDR2 si v0>v1

  } while(1);

Look's like your program even not start. Possible, because MCLR pin used in configuration and connected nowhere. Use pull up resistor at least. For simulation only you can connect MCLR pin to VCC directly. Proteus doesn't simulate startup reset pulse, crystal oscillator, coffe machines and e.t.c. It using SPICE engine whith some primitive microcontrollers options.
 

well i used the pull up resistor but the problem doesn't solved
I didn't understant what do you mean by " using SPICE engine whith some primitive microcontrollers options."
 

"Grey" designates unknown state, e.g. floating input. If it's observed with pins that should be initialized as outputs, it means that the code isn't executed regulary. To see why, you can load a *.cof instead of *.hex file and trace program execution in Proteus source level debugger.

Although I won't contradict the Proteus qualification by Easyreader83 as "SPICE engine whith some primitive microcontrollers options", even this primitive options can be helpful if used intelligently.
 

Binary file 1.hex is missing, you should also attach the debug binary 1.cof to allow code debuuging.
 

Zip and attach the complete mikroC project. We need to see the configurations you have set.

What are all the semi colons (;) after while(1) and if() conditions ? Proteus 8.1 file attached. Proteus file has been modified.

There are several errors in the schematic!!!
The diode bridge is connected wrongly, the 12V supply shorted to 5V (all is named as VSS???), the relay coils are without power of 12V, the ULN2003 connected wrongly, etc...

These are my suggestions for the schematic (Proteus 7.10SP0):

Using only one ULN2003A:
