4 digit up/down counter kit, using atmel uc K129
using an Atmel microcontroller
This kit was reviewed in Silicon Chip, April 2001. Kit 129 and k154. Microcontroller-Based 4-Digit Counter Modules
Open collector output is used in k129 and k154. For a discussion of open-collector output get this text file
The first in a series of counters using uC's. This kits clearly shows how uC can more than replace a host of ordinary logic IC's.
