I know its not that hard,but I am concerned about the thing that ,,would the ckt b able to provide equal current to so many LEDs as shown in my diagram above few posts

your button press starts a sequence on the tiny13 (yes AVR). The tiny shifts the register and the register switches transistors that drive your LEDs.
You should use a serial input parallel output shift register.
Or you use smth like the Atmega8 and switch the transistors w/o the shift register. This would probably be easier for you.
