Yes sir.

It has RF433X which gets data from HT12E encoder which gets its data from PIC microcontroller.But how is PIC microcontroller able to send the data to HT12E about which lane is the ambulance travelling?

Acoording to the link i have put in the post,It said the driver has remote where the lane number is selected.But how is that remote connected to PIC microcontroller ,This we are unable to understand.

Hello sir

Thank you for the reply.

Well I was asking about how is the remote conneceted to pic microcontroller in the ambulance unit?

We also have a code regardinmg this in which three colours for the traffic are mentioned.

#include “reg51.h”
#include “define.h”
main()
{
Initialise();
while(1)
Traffic_Light();
}

Traffic_AC()
{
here:
YA=0;YC=0;YB=0;YD=0;
GA=1;GC=1;GB=0;GD=0; //A and C side Green; B and D side Red
RA=0;RC=0;RB=1;rD=1;
if(count<50)
{
if(Input==0)
{
while(Input==0);
if(A==1 || C==1) //Ambulance from A or C side
{
Traffic_Light();
}
if(b==1 || =1) //Ambulance from B or D side
{
Traffic_Light1();
}
}
goto here;
}
count=0;
}
Yellow_BD()
{
here1:
YA=0;YC=0;YB=1;YD=1;
if(count<20)
{
if(Input==0)
{
while(Input==0);
if(A==1 || C==1) //Ambulance from A or C side
{
Traffic_Light();
}
if(b==1 || =1) //Ambulance from B or D side
{
Traffic_Light1();
}
}

goto here1;
}
count=0;
}
Traffic_BD()
{
here2:
YA=0;YC=0;YB=0;YD=0;
GA=0;GC=0;GB=1;GD=1; //A and C side Green; B and D side Red
RA=1;RC=1;RB=0;rD=0;
if(count<50)
{
if(Input==0)
{
while(Input==0);
if(A==1 || C==1) //Ambulance from A or C side
{
Traffic_Light();
}
if(b==1 || =1) //Ambulance from B or D side
{
Traffic_Light1();
}
}

goto here2;
}
count=0;
}
Yellow_AC()
{
here3:
YA=1;YC=1;YB=0;YD=0;
if(count<20)
{
if(Input==0)
{
while(Input==0);
if(A==1 || C==1) //Ambulance from A or C side
{
Traffic_Light();
}
if(b==1 || =1) //Ambulance from B or D side
{
Traffic_Light1();
}
}

goto here3;
}
}
Traffic_Light()
{
Traffic_AC();
Yellow_BD();
Traffic_BD();
Yellow_AC();
}

Traffic_Light1()
{
Traffic_BD();
Yellow_AC();

Traffic_AC();
Yellow_BD();

}

Thats why we are confused with coulour and number of LEDs.

I request you to please look into it.

Thank you.
