Morse code speed indicator

[AlbertoFS]

Sometimes morse keyers do not have the possibility of knowing at what speed they work. This project allows you to measure the speed of your keyer.

This project consists of a microprocessor based circuit to measure the speed of your keyer.
Two projects are available:
The first uses the classic displays and standard components.
The second uses a display with 74HC595 interface.
All documentation and firmware is provided so that users can assemble this project themselves.
