hello sir

i have observed that there are a lot of extra components in the image of circuit than as shown on circuit diagram.
Now i am in confusion.....i need your help.
i want this project to be working for me.......for this i need the final list of electronics components required.
u are requested to mail me the list of components or comment here below.
my email id is- [email protected]

the project is not so complicated to make ....if u observe it fine...
just construct the ...basci ckt for microcontroller as done as usual......
if u buy a 5v compitable Bluetooth module the no need to use the zener or 3.3v regulator....
now....connect the BT serial pins to micro serial pins....
port2 o/p to moterdriver ckt ....use 4.7k pullup resister for port2...

for more info....see the data sheet for respective item

AT89S52...1
Bluetooth module......1
22pf cap....2
11mz crystal...1
4.7k resisters ....8
7805......1
LEDs....6
L293D...1
connectiing wires...
this all r required components...to start the project...

can u provide me the updated ckt diagrams for it....because the ckt diagram attacted with it does not show any capictors and 7805.
u can see the attachment of ckt diagram

i have made the ckt keeping mind that any one would make this project may have the basic knowledge of microcontroller ckt..
and ..what exactly do u want ...

can u locate the capictors and 7805 in this ckt diagram....in the attachment

there is no question of locating the 7805 and crystal and its cap as i have mention a sentence...n the reset ckt also..
here is the link for reference

i am beginer....i must clear u it.......if i just made connections acc. to ckt diagram in the attachment...ie without capacitors, crystal and 7805.....will the ckt work???
if no.....please provide me exact circuit.

in the 6th post i have attached a image ....for connections for crystal..7805..and capps

plzz u are requested to modify this circcuit diagram....i am unable to understand the above image

No, it will not work.

Gaurav.k has left some components off his diagram to avoid clutter.
He has left off details of the power supply ,reset and the micro's crystal.

He has posted a circuit above, showing the extra connections needed.
Add these items to your circuit.
Use an 11.0592Mhz crystal, not the 12 Mhz shown.

On the 7805, add a 470 uF 25 volt capacitor between input and ground
and a 22 uF 16 volt capacitor between output(5 volts) and ground.
