Digital Km-Step Counter / Nik Mohd Izafudin Shah Nik Mat

A counter is a one of the most useful and versatile subsystem in a digital system. A counter driven by a clock can be used to count the number of clock cycles.
This project is about the DIGITAL STEP-KM COUNTER. I only make a model which function and it concept is similar with commercial product. It only a basic model and hope it can be upgrade to better equipment.
This project is a small box that slipped in pants pocket to measure the distance during a walk. It display distance from 0 km to 9 km. It have 2 LED mini display, one show hundred meters and the other show the km. In every 50 meters of walking this LED will be light.
In every 2 step, a beeper will occur. For low consumption, the display light only on request, we can use P2 switch. For reset the circuit we must push both button together. This will avoid accidental reset of the counter.
Applications of this project is, we can use it in sport during training and to everybody who want to keep health.
