FIRE FIGHTING ROBOT

hellow ajay ive chosen the fire fighting robot frm ur tutorial section as my project.
i wana kno if this circuitry works fine and d code is correct??


well whts J1, A and capacitors C2 C3 C4???? whts U1.....U7???
and wht type of IR sensors r u using??!!!

the author says he/she has posted a new and updaed link and circuitry!!!on d website!!but where is tht link??:s m so confused!
i have all the parts with me need to sold em but let me kno if this code ns tuff works fine plz

well there was a missing circuit in the zip file Please download the file again.. his site is still missing it.. but i have the files and i updated it.. he claims that circuit works.. but as i look into the code. there are errors... If you are interested then we are here to help you with the coding.. to make it work..

ok ive just downloaded the new zip content....it has three more circuitries!

i reallly need to work on it but i lack time!!!
im looking for som small circuit n coding for my project!!!
is there any other solution?
i mean like
the ir sensors detect heat and report it to a port on the 89s52 which inturns activates the fan on the other port???

well... you can make something simple using that project circuit..
no need to make a moving robot.. rather you can have a simple automatic fire extinguisher.. how bout that..?
or automatic fire extinguisher and alarm? that will be simple to make but good as per the application is concerned.
So tell me if that is ok I will help you in making it.. its really easy to do..

yea sure tht will be veri helpful........a simpl heat detector n moving fan is wht i require the most
plz plz letme kno bout the circuit and the coding m waiting
plz prvode the coding in asm

well i am not going to provide coding... you are going to do everything yourself.. but i will give you all kind of help needed, like i will check your code.. write or wrong.. if any changes needed i will do it for you.. I will provide you references that will help you to complete this project..
Things you have to do are..
search... look for data over internet.. Sure you will find many things.. and read a lot

So things you need for your project...
1. Smoke Detector
2. Temperature sensor
3. An actuator circuit...
4. Alarm circuit
5. Controller

Above are the main things constitute your project... coding comes to the last first you need to make your hardware modules ready.

ok no code!!!! :mad :mad :mad

well ive bought AT89s52 and ADC0809 and some reqired resistors capacitors n Ir detectors

wht options do i hav ? whts the most simplest project i can work on?
i really dun hav time:s

hey i hav this circiut and its coding
as said in its description wen the button gets pressed it will turn the LED on n den off



and here is its code

Program to turn on the LED when the button is pressed once and to turn off the LED when it is pressed again

ORG 0000H ; Execution starts here
LOOP:SETB P0.4 ; Make port P0.3 as input port
MOV C,P0.4 ; Get the button state to carry bit
JC LOOP ; check if button is pressed
CPL P1.6 ; if pressed compliment the port
JNB P0.4,$ ; Wait until the button is released
SJMP LOOP ; do it continuously
END

i wud like to kno if i can put a heat detector instead of tht button and a motorised fan instead of tht LED?
wht changes to the circuitry do i need to make then?
can u help wid the stuff now?
i wonder if i need to change my AT89s52!!!....or will this code work on any mcntroller ic?

yeah.. you can do that...
make smoke detector with the help of IR LED and photo transistor.. or make use of TSOP circuit and NE555 circuit from the project you downloaded.. Please take a look at this website to know more about a smoke detector design..
http://home.howstuffworks.com/smoke1.htm
Check out the simple design of Photoelectric Smoke detector Hope this will help you... I am sure you can do it

well i tried convincing my professor for the abuv assignment n he refused

so i worked on another project thts....controlling a two stepper motors using push buttons in cw and acw motions



and here is the coding tht ive done...n checked it on keil..it seems to work for me....

org 0h
main:setb p2.7
mov a,#000001111b
mov p1,a
turn:jb p2.7, acw
acw:rr a
acall delay
sjmp turn

main1:setb p2.6
mov a,#11110000b
mov p1,a
turn1:jb p2.6, cw
cw:rl a

main2:setb p2.5

mov p1,a
turn2:jb p2.5, cw1
cw1:rr a

sjmp turn2

main3:setb p2.4
mov a,#11110000b
mov p1,a
turn3:jb p2.4, cw2
cw2:rl a
acall delay
sjmp turn3

delay:
mov r2,#100
h1: mov r3,#255
h2: djnz r3,h2
djnz r2,h1
ret
end

the stepper tht im using is 6wire

now i want to keep the stepper movin till ive kept the button pressed...either in cw or acw button whichever is pressed.

can u also help with the schematic tht ive pasted?does it need changes or is it completely wrong?
time is short my side :-s
il b looking forward for ur assistance :-)
