What type of counter do you want, binary or decimal? What should be the
maximum count?
What are your power requirements? What speed does it need to count?
Do you need to count up and down? Do you need to be able to preset a count?
What
type of display, if any, do you need? |

Not having more specific information about your needs, I'd recommend
the Velleman K8035 Multifunctional up/down counter kit. It probably
has everything you want, including preset output. If you want a spiffy
job, get the bezel, too (B8035).
You might also want to download the manual. If nothing else, it will
give you ideas on how to ask for what you want.

Good luck

Parts are by mail order from many sources...try www.digikey.com
A counter normally starts at zero and increments through its max
count and then returns to zero. Do you really want to count 1 through 9?
The CD40160 should work well...use the carry output to preload
a 1 into the counter. You will need a decoder to convert the BCD
into a 7 segment pattern for use with a 7 segment display. You will
need a few more passive devices and a power supply to make it go. |
