PROJECT DEFINITION / SPECIFICATION
SECTION 1: PROJECT TYPE
Micro controller (AT89C51) hardware design with software development (Device Driver).
SECTION 2: PROJECT DESCRIPTION
In modern days many automatic devices require timers for the proper operation of the devices. Presently all the world is going into automation. In this project we are designing a count down timer where you can start the timer and view the timer. In this timer we are keeping one buzzer to give buzzer for every one second. As an advanced application we can also use the same device as a timer.
SECTION 5: PROJECT OUTLINE
Ø A brief introduction to internal architecture of micro controller.
Ø An over view of programming of micro controller.
Ø An overview on assembly language.
Ø An overview on interfacing SEVEN SEGMENT.
Ø An overview of Buzzers.
Ø An overview on interface of switches and led.
SECTION 6: INTERFACES USED
Ø Sensors interfacing.
Ø Seven segment interfacing.
Ø 4x3 Hex keypad interfacing
Ø Buzzer, switches, led interfacing with micro controller.
SECTION 7: SOFTWARES USED
Ø A Cross compiler for compiling and linking the code written for AT89C51.
Ø Serial communication software for downloading code to AT89C51.
Ø Operating system: Windows XP.
