Golf Scorecard LoggerGolf Scorecard Logger

Supervisor: Alan EdgarNapier University

Introduction:

To automate and ease the scorekeeping of golf players matches for calculation of individual handicap scores and statistical illustration, a hand-held electronic scorecard logger unit is developed, with the implementation of the 1-Wire bus and iButtons. The logged data is downloaded to a PC, where the handicap is calculated and statistical data saved to illustrate the players progress over a period of time.

-This will open up new opportunities for golf players of storing and analyse the scores, where improvement can be tracked.
