AVR microcontroller based conference presentation timer

Abstract

In this paper an implementation of an Atmel AVR based Conference Presentation Timer (CPT) is discussed which will serve as an automatic time keeper that keeps the track of time during presentation in a conference or seminar and alarms the speaker accordingly. Usually the duration of conferences vary therefore a provision of adjusting the total time is kept as well as a facility for changing the alarm time is also kept. However this paper elaborates a prototype which has further scopes for improvement.
