Hi i have just started learning arduino and i am trying to setup stand alone on breadboard as in tutorial https://www.arduino.cc/en/Main/Standalone my problem is when i uploaded a sketch from my UNO the led on pin 13 is blibking but when i put it on breadboard it does not work i have everything setup as guided in the tutorial and the other led for power indication are lit up but not the blinking led on pin 13 please help

How about a picture of your setup?
At first sight looks like side supply rows are not connected together (+ with + and - with -). Also I missed decoupling caps.
i tested with multimeter both side are connected with 4.9 volts and from the tutorial i double check and i am sure that i put every component as in tutorial anyway thank you so much for your i will try to set it up again and post the result later
The tutorial omits the decoupling caps, I have no idea why the guide has not been fixed (we routinely correct people about it on the forums); these are necessary for proper operation (though I'm not convinced this is your problem - it could be; it's hard to tell if the chip is doing nothing, or resetting itself every time it tries to turn on the LED). 2x 0.1uf ceramic caps. One between Vcc and Gnd, other between AVcc and Gnd, right next to the chip.
Is the LED the right way around?
Measure voltage on reset, make sure it's ~Vcc, and make sure crystal is making good contact. Sometimes on breadboard, due to stray capacitance, you need to remove the loading caps on the crystal (depends on the breadboard and other voodoo - one of many reasons I despise breadboard).
Thank you DrAzzy maybe what you said is the problem i will try and let you know the result
Your Fritzing diagram shows the ground rails on either side not connected and we cannot see in the photograph whether you have done so. That would be a bad mistake. And yes, your bypass capacitors are missing.
You show Vcc connected to Aref on chip pin 21. It should not be.
After these you may need to try without the crystal capacitors!
Thanks for the help finally got sometime to test it again and as all of you suggested the decoupling caps was the problem as soon as i plug it in the thing start working Thank you very much and 1 question why did they omits it in the tutorial i think the issue give a lots of trouble to newbie like me
It's as if these people don't try it themselves before they post them....

Are you op?

The similarity in "handles" would suggest so,
I suspect people sometimes forget what name they used - or password - then suddenly remember. I can empathise to some extent.
Hi Everyone,
I have got this interest and i am learning about micro controllers more and more. Recently when i wanted to buy an aurduino starter kit, i got an aurduino UNO which looks different that the usual one. Photo is attached.
Currently i am trying to burn boot loader on a new ATMEGA 328P-PU micro controller with this aurduino UNO.
I have followed the guidance being provided on this link. http://www.crash-bang.com/resource/bootload-atmega328/
The boot loading effort are of no avail.
Request your expert advice to guide me through.
Also please let me know if any additional details are required from my side.
Thanks

A fritzing schematic is required for better understanding, because the picture quality is poor.
Another tip: You should use this cables instead breaboard jumper/cable.
Did you check your connections with a continuity tester?

Well, pretty clearly that can in no way be called an Arduino UNO; it does not have the components of an Arduino UNO.
That is not critical - it should certainly be functional; I am only pointing out a detail - "call a spade, a spade".
The best guide to this process is Nick Gammon's.

Your circuit has the same problem as OP's - you have omitted the decoupling capacitors (0.1uf ceramic, between Vcc and Gnd, and between AVcc and Gnd, as close to the chip as possible), probably because you followed a guide that didn't include them... (that's what we were complaining about in the last couple of posts before you posted here)
