Timer for two Air conditioners

Your LEDs are connected to RC4 and RC5 but you're trying to blink RC0 and RC1. Your delay is 10s and 5s, Isn't that too long for blinking LED?

Code:

void main() {
  TRISC=0x00;
  PORTC=0;
  do
  {
    PORTC=0b000011;            // should be 0b00110000
    Delay_ms(10000);
    PORTC=0b000010;           // should be 0b00100000
    Delay_ms(5000);
    PORTC=0b000011;          // should be 0b00110000
    Delay_ms(10000);
    PORTC=0b000001;         // should be 0b00010000
    Delay_ms(5000);
  }while(1);
}

#include <htc.h>

void main() {

  PORTC=0;
  do
  {
    PORTC=0b00110000;  // both LED off
    __delay_ms(1000);       // delay 1s
    PORTC=0b00100000;  // LED1 on LED2 off
    __delay_ms(500);         //delay 0.5s

I am doing a timer for two Ac s.
PIC used is PIC16F676
environment used is Mikro C

AC hase 5 phases:
1) both AC ON for specified time
2) one ac on other off for spacified time
3) step 1 repeat
4) step 2 repeat but ACs are alternated
5) loop repeats

In proteas the ports do not turn on. they just show grey color

code :

Code:

void main() {
  TRISC=0x00;
  PORTC=0;
  do
  {
    PORTC=0b000011;
    Delay_ms(10000);
    PORTC=0b000010;
    Delay_ms(5000);
    PORTC=0b000011;
    Delay_ms(10000);
    PORTC=0b000001;
    Delay_ms(5000);
  }while(1);
}
