I am facing a "Nothing Happening" kind of problem and that is...
I am trying to put the Atmega168 over Breadboard. It is Pre-installed with Arduino Boot loader.
Trying to plant the BAREBONE circuit over breadboard but its not happening.
Means the chip is not getting boot-up. That is PIN 19(SCK) is not emmiting Volts over my LED which i have connected.
overall, the chip is not Getting start, i think!
Enclosure:
a snap of my Breadboard Setup.
A circuitry diagram which i am following while putting components on to breadboard.
please correct me where i am going wrong or so.
Diagrams which i am following is from Internet.
i have burnt the Sketch into chip by placing into Arduino board, then i detach the MCU and placed it onto breadboard.
now i want my MCU to do according to the program which is already there in.
after fitting all over breadboard according to requirements, my MCU is not showing any activity or so.
now i want my MCU to go alone on its own but its not happening and i am powering my breadboard externally with help of 7805 IC n a battery!
So, assuming you have the LED wired in series with a resistor to +Gnd (neither the picture nor the schematic show what is connected),
and the Reset pin properly pulled up to +5V:
Post you sketch so we can see what you are trying to do.

Leave out the spaces between the brackets, and it ends up like this when you click on Post:
The thing is my MCU is not starting UP!!!
and hence my LED over pin 6 i.e pin4 on Arduinois not Glowing up.
One more thing is: while the Bootloader is been detected or found! the SCK....19th pin blinks up fastly na?!!!!
That also not happening!!!!!
Rest, the current condition is same as before....!!! not working!!!
and the other side of this is when i place my CHIP back to ARDUINO BOARD, its works fine! =(
Well it's not the same is it? I don't want you to assure me that you have the "same" setup as me, and in the next breath talk about a voltage regulator and an LED.
Your capacitors in the Crystal oscillator circuit are shorted to themselves and then to ground. The holes are connected vertically. You need to move one leg of each capacitor to the hole that is closest to the ground bus and then place the other leg of the capacitor into the ground bus.
Pin 1, reset, is tied to +5V directly. You need to fix this circuitry.
These are 2 errors I have found. There could be others.
