I want to design a system that when it senses motion the lights will be automatically switched on and then off when no motion is detected. can I use PIC 16F877A and how? Thank you
 


plz insert a pull down reistors of 10k to rb0 and rb1
the block j4 is a switch when it is on it means that the door is locked and if there any motion detected the buzzer and led activated and when the j4 switch is off and any motion detected by the pir the mc doesnot activate the buzzer and led.

for this project i write the code in mikroc pro for pic
Code: 
void main()
{
 TRISB=0x0f;
 PORTB=0;
while(1)
{
   if(RB0_bit)
{
   if(RB1_bit)
   {
   PORTB=48;
   Delay_ms(300);
     PORTB=0;
     Delay_ms(100);
 }
 else
   PORTB=0;
 
}   }

hope this will help you. . . any queries plz ask

Such systems are commercially available: PIR detectors, with adjustable on and off delays. Available in hardware stores, $10-25 a box.
