use counter chip cd 4040 or else

use Q4 /Q5 /Q6

Thanks....

Hi can u ... explain a little more...

wat is that Q4/Q5/Q6???

Y do u say 555 astabble is better???
 

ADC0808/9 i am used 400-500 times, a good exp abt it.

while driving its clock from xtal , there may be a problem of interfacing of such high frq, signal to the ttl ckts , . still req one chip .

so go for separate clock using 555 , 2 r , 2c, 1 d ....cheap too and can be treble shout easily if there is any problem
 
it is really helpful thanks guys
 

555 in astable mode is cheaper and easier, you can calculate the values here:

**broken link removed**

Try Vcc=5; R1=1,2; R2=1,8; C=600

Use the timer/counter module of your micro.
