PW Sim

PW Sim : LOCK & UNLOCK Keypad, LCD interfacing

This is simulation done by Wiztech students during our embedded training slot.  The projects involve the application of 8051 microcontroller in keypad based security system for home automation.

Port Connections as follows:

Port2 – LCD data pins

P3.1 & p3.3 – control pins

Port1 – keypad

When the authorized person enters the 3digit pass code to access the next routine. The lock status  is displayed on LCD.

Tools :  Simulation is done using Proteus ISIS

Program is developed using Keil vision3

GSM Notice Board

This project is a simple GSM Based project where 20x4 LCD is used as display for Notice board and GSM modem is used for receiving and sending SMS. When a user wants to display a notice/message on the notice board, user will send sms from a verified mobile number and sms recevied is displayed on LCD. Project involves simple security feature where SMS sender's number is compared with a pre-configured number (hardcoded in source code). If sms is recevied from an unknown sender, a notification SMS is sent to pre-configured number notifying an invalid access to board.

This project is fairly simple but its main purpose is to demonstrates reading and sending SMS using GSM Modem. There are many users on forum who struggles getting SMS read working in their projects. So For them this project is a starting point. - See more at :  http://bestembeddedsystemtraininginchennai.com/
