Hi Abhinav, you can use either the 7447 or cd4543 chips to drive a common anode display. The problem with these is they don’t have a carry out pin, so you need to add gates that detect when you have reached a count of ten. I haven’t seen a chip the drives common anode with a carry pin. Another option is to add inverters to the output of a chip for common cathode type display, this will work. Otherwise you need to use a microprocessor to control displays with no carry pin. Why not just use common cathode displays? They are cheap as dirt.
What Push button is that.. I tried with 4pin push button but it didn't work Can u send me the link or smthgelse regarding this push button Am too much confused here
fantastic im going to build this for counting how many parts i throw in a parts bin with a microswitch in the chute to send the pulse
what segment display is that? i need 10 that size
FJ5101AH You can find them on dealextreme.com
Sir. Could you please explain 3 digit circuit of common anod 7 segment display like this one?

This is just a normally open bush button switch, any two pin type will do.
