sir i zipped all the files.

you forgot the hex file.. can you tell me what problem are you facing in this simulation..?

sir this simulation doesnot shows any output i.e siren(buzzer) is not beeping, lights were not working.I have uploaded the hex file that i use in this simulation. Plz find it and download it.

Some of the components you've used in proteus schematic does not have simulation models like 7805, 2N2369. So your 5V power rail was not generated properly and secondly LDR logic is not working.

In simulation you can cut down things like.. all the LDR circuit will give either high/low depending on light conditions. So you can replace the whole circuit with a SPDT switch where one end is connected to VCC and other to ground. You do not have to simulate relay with exact voltage levels as its just a simulation so connect 5v to relays while testing. So you do not have to create new power rails in simulation. So I suggest you to redesign your circuit with just the logic that is needed.

sir i have also one more query regarding this project.
as size of AT89C2051 uc is 2kb but the size of hex file naming password.hex is of 3kb.
is it ok?as project is not running properly.
plz help me sir.....

sir plz also tell me the type of 7 segment display used in the circuit.

Hex file has got ASCII data which is converted to binary by the flash programmer. So the size you see is the size of hex file not the actual code inside it.

Regarding 7segment display see the schematic if common of segment is connected to vcc then it's common anode and if common pin is connected to gnd the it's a common cathode type segment.

When I m trying to burn the hex file to the microcontroller then hex code is not properly taken by the microcontroller I.E in buffer section (this section is in the "topwin 6" software which I used to burn the microcontroller,
as it is the part of "top universal programmer" ) it is not showing proper hex code but when I take at89c51instead of at89c2051 then it show proper hex code....
As I have made the pcb of 20 pins and I don't have much time to make another pcb so what can I do to burn the hex file in at89c2051????

There are two hex files in this project. which one are you facing problem with? moreover both codes are written for 89C2051 so ideally you should not face any issue while loading hex files.
