Step 3ASEMBLY
I highly recommend laying this out on a proto-board first, like the one below, just so you can play with the values without having to unsolder stuff continuously.
Start by assembling the 555 circuit first to assure that you have a working "pulse". connect the resistors and capacitor. then run a LED between pin 3 (positive) and ground. then connect the power. If everything is right, the LED should blink. If not, disconnect the power and check all your connections.
Once you have a pulse, connect up the counter IC. output of the 555 (pin three) to pin one of the counter IC. then connect a few LEDs to the output pins. add jumpers as per the diagram for the power and see what happens. the LEDs should start blinking somewhat randomly. If not, disconnect the power and check all your connections.
Once you have pretty blinking lights, you could just stop here and solder it up. I'm not going to go into techniques for layout or soldering. There are a lot of other great tutorials in here for those skills, and it's getting late. I'm sleepy.
If you want the fade effect, then it's time to start wiring in the extras.
First, wire in the diodes. this is important, as you don't want the capacitors discharging back through the counter IC.
start wiring in the capacitors and resistors. Play with different values to get the effect you want.
Oh, and before anyone asks me, the animation below is a GIF. I made it in Photoshop, but there are a lot of other software packages that can do it.

thanks having trouble converting circuit diagram onto bread board ,do have any suggestions
