Project Duration: [PLEASE FILL]
Organization: [PLEASE FILL]
Role and Designation during the time: Team Leader
CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
I designed a digital stopwatch using the microcontroller ATMEL 89C51 and seven-
segment LEDs for the purpose of display. I implemented my leadership, management, and
engineering skills for the design of a stopwatch that could be used for the daily purpose. I
implemented C code for the microcontroller circuit for digital stop watch as mentioned in the
following sections. I incorporated a switch on the circuit of the digital stop watch that will allow
it to function same as that of the general stop watch and allow the accomplishment of the
specified job. I built the system that will allow the user to start the stop watch from the beginning
after pushing the inbuilt switch. I embedded C coding within the microcontroller for the
management of all the functioning of the stop watch.

CE 3.2.2 Objectives developed for the project
Following were the set objectives for the successful delivery of the project and efficient
application in the real world:
To use ATMEL 89C51 for the development of the digital stop watch
To embed the C coding within the microcontroller
To propose a real world applicable stop watch
To deliver the project within the estimated timeline
To manage the team members and motivate them towards achieving the goals
CE 3.2.3 My area of work
I was chosen as the leader for the team and it was one of my prior jobs to manage the
team involved in the project and assure that everyone is contributing evenly throughout the
project. I had to manage the chip layout of the AT89C51 microcontroller and make the circuit
connections for the microcontroller pins. I developed the circuit diagram of the entire project that
was helpful in demonstrating the schematic representation of the circuit connectivity based on
which the rest of the team delivered the necessary work. Following is the developed schematic
diagram:
