0 to 99 counter

I want to make 0 to 99 counter using 4029 and some other necessary
chips . How can I do this ?

This should be relatively easy if you have the CD4029's already. One
of these chips can count from 0 to 9 provided you set the BINARY/
DECADE (pin-9) to a low level. Also put the UP/DOWN (pin-10) of this
part to a high level to enable counting in the upwards direction.

Counting to 99 will require two of the CD4029s. Connect the pin-9 and
pin-10 of both parts as discussed above. Also wire the PRESET input
(pin-2) on both parts to a low level. Wire the clocks in common to
both parts and connect to whatever it is that will advance the count.
On the first device (low digit counter) make sure to set the CARRY_IN
(pin-5) to a low level. Then take the CARRY_OUT (pin-7) of the first
counter and wire it to the CARRY_IN (pin-5) of the secound counter.
This latter connection allows the second high digit counter to step
only when the low digit counter is rolling over from nine back to
zero.

Since these are CMOS parts it is advisable to also tie all of the
JAM_LOAD (pins 3, 4, 12 and 13) inputs to low levels at both chips.

For the basic counter you desire no other chips should be required to
implement the 0-99 count sequence.

Sell the chips and buy a Basic Stamp, of course.

Zing! Yeah what's the deal with 4000-series CMOS in 2007?

Use a PIC micro controller, and glue the 4029 on top.

Get two 4029s, and connect them together in the right order.

Good Luck!

Apply wire, solder, power, and a little book learnin'...
not necessarily in that order...

It doesn't matter which order the 4029s are connected. ;-)
