thanks a lot

should i insert all the wires deep inside the breadboard or just a little bit going inside is enough

Remove 1/4" of insulation from each wire. this 1/4" bare wire should go into the breadboard.

Nitesh, your breadboard's positive and ground rails might be split into two sections, in that case you need a couple of jumps in betwee, where the're split.

You can find out the split point with the buzzer mode on the multimeter, just check for continuity/conduction on those two rails.

I did all the connection as mentioned by anjan bhai but it didn't run I was so sad but still i am going to finish it although the last date for the submission is over. I think the isssue is with the connection the wires are not at all going inside

Bro go here this is how the breadboard is internally wired, you will need to make jumps between connections.

Follow anjan bhaiyas connection diagram and dont insert the wire with insulation inside the breadboard, remove 5mm - 10mm insulation off each wire end before inserting how in you go doesnt matter but the deeper you put the wire in the better the connection.

I would suggest prototyping it on a veroboard/stripboard so you will have a good connection for sure. Though if you dont have basic soldering skills stick to the bread board and push the wire end in as much as possible for a good connection.
http://en.wikipedia.org/wiki/Stripboard  - for info on veroboard.

Strip the insulation off the wires to expose at least 5mm of conductor. Use single strand wire.

You're problem might be caused by what I have mentioned in Reply #28
Here's the edited schematic, only 4 extra connections.

After you do the necessary modifications to the circuit, If you have spare 555 ICs, replace both the ICs and triple check your connections before connecting the battery.
Gently touch the components to make sure nothing is getting hot.

Good luck.

Added the jumps between power rails anjan bhaiya
Should have let nitesh figure that one out

I didn't put the wire with insulation I have little bit of brain to know that i should not put it with insulation .I have the veroboard with me actually two of them and i am ok in soldering but I want to finish this in the breadboard and not on the pcb board or the veraboard.
One question do we get jumper wires in india i saw them in an youtube video one guy used it on the breadboard.

Thanks anjan bhaiya but I already added the jumps.
there is no relation of jumps with the first led not lighting there is surely connection problem with my wire. Actually some wire went inside totally but some just went only one or two mm so i think the issue is with those wires.  I am going to buy another wire today and do it again.

You can get male-male jump wires for breadboard. It's cheaper for you rather get some single strand wires, mention to shopkeeper that you need it for breadboard.

Except the first one, did the rest of the LEDs light up?

not even a single led lit i waited some minutes but they didn't

The first LED does have relation to the jumps. Pin8 on the first 555 is connected to the +ve power rail on the other side so all four jumps are required.

ok but my thing didn't light I'll try it again
so lets wait for sometime

Go to your local hardware shop and buy single strand copper wire.
Use that in bread board as jumper wire, works well.

The jump wires are even available on ebay. Saw it yesterday while doing random search.

Nitesh Man,
It shouldnt be that Hard to make this connection. its the simplest one and you should be doing this already with your knowledge.
Okay now, there isnt any special wire for jumper, if you live nearby adyar, go to Mercy electronics and ask for breadboard wires. get 2 meters for 20rs. use it to connect breadboard.
make sure you have a quality breadboard, cheapos will give all sort of troubles.
Chek your batt voltage. is it from 6-9volts. chek the basic blink LED circuit for 555 to make sure the IC and everything is working fine and then complicate it.
Best of luck buddy.

Sir yesterday I went to jency electronics this is the shop from where i buy most of my electronics this is situated in eldams road very near to my house just a five minutes walk.
So yesterday I went there and asked for breadboard wires but that guy told it is not available with him so i just asked him to give me single strand copper wire and he gave me some hook up wire which are just awesome they go deep inside the breadboard.
Also the breadboard I am having is this one http://www.ebay.in/itm/Breadboard-840-points-Solderless-DIY-Project-circuit-test-Bread-board-/121085654742?pt=LH_DefaultDomain_203&hash=item1c314476d6&_uhb=1is this good or bad i got it from ritchie street. also the wire is this one http://www.ebay.in/itm/Single-strand-breadboard-hookup-jumper-wire-for-Hobby-or-Academic-Projects-/221315599355?pt=LH_DefaultDomain_203&hash=item3387700bfb&_uhb=1#ht_1909wt_1271 I got it for 30 rs. for 5 colours this is the exact one as I can identify it from the pic on ebay and the one which I am having especially from the tape in which it is written conel.

The breadboard is good. I've been using a couple of those for 3 years now and they're okay.

I finished everything but now one more issue
only one light is lighting that is the red light other lights are not even lighting.
will try putting a video

Keep running through the circuit connections. Check for the polarity of the LEDs.

couldn't upload to youtube don't know why

Thanks to everyone for their help my project worked out very well I found that there is some issues with the ic and the connection was loose.
now it is working very well although the lights are very dim.

Special thanks to Anjan Babu and ak.stunns
