677 : Simple counter
- Author: Karl Herman Krause
- Description: Simple counter running at approximately 1 Hz, output wired to 7segment

- Clock: 10000 Hz
How it works
The circuit uses a clock divider to generate a aprox 1hz clock which drives 4 registers. The register outputs are routed to a full-adder, and the counter value is incremented by 1.
How to test
NA
External hardware
The project uses the external 7-segment display.
