| Abstract: | This project presents the design and construction of a digital countdown timer with alarm. An AT89C52 microcontroller IC belonging to the 8051 family was programmed as a real time clock. The digital countdown timer can count down from as high as two hundred and fifty six (256) days to zero seconds. When the countdown is completed it sounds an alarm, signalling the end of the countdown |
