Arduino based GPS data Logger


Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. This is a very simple project based on Arduino and GPS sheild combo. Arduino provides good set of libraries which are easy to use and you can include in your project without any hassle.



As GPS usually works on serial ports, Software emulated serial port is used to connect GPS with arduino running at 4800bps. The hardware serial port is connected to PC for serial data logging. A 16x4 LCD is used for displaying GPS data locally. LCD provides GPS information related to Latitude, Longitude, Altitude and speed.



Its a very good project for starters, who wants to get their hands on with Arduino. I would like to thank Santosh Mishra for submitting this project. Hope to see more contribution from him.

Metro Train Prototype Project with Project Report





It has been a long long time since I posted a new project on our website. Today I looked in to all my old emails and checked all pending projects which were not uploaded. I want to thank Gaurav Sharma for submitting this wonderful project. I Hope to see more contribution from him.

Metro Train is one of the biggest transporation medium in Delhi connecting all ends of Delhi together. This project is a very simple train prototype of current Metro Train. This prototype is powered with 8-bit 8051 microcontroller. As you know Metro trains run in one direction at a time, so prototype uses only one motor to move the forward. There is an additional motor which is used to open and close the doors of train. LCD is used to display welcome message, current station and next station messages. A buzzer is there to indicate opening and closing of doors.

Working Of Metro Train:

When the power is turned on a message ("welcome to Bhopal metro") is displayed on LCD. Then a message "Current station is Indrapuri" is displayed and door is opened. A buzzer is also turned on when door opens. After some delay the door is closed and car is started to move forward. A message "current station is Indrapuri" is displayed also on LCD. After some time a message indicating the next station is displayed "next station is M P Nagar". After some time the train stops and a message "current station is M P Nagar" is displayed. This process is continued for five stations. In the end a message "End of line" is displayed on LCD. This whole process is repeated until we turned off the power supply.

A big thanks to Gaurav Sharma for submitting this project.

The digital IC tester is implemented by using the 89C51 microcontroller board. The processing of the inputs and outputs is done by the microcontroller. The display part on the microcontroller board is modeled using LCD. After the successful testing of the IC, the result is displayed on the LCD.

The basic function of the digital IC tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. It can test digital ICs having a maximum of 24 pins. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This model applies the necessary signals to the inputs of the IC, monitoring the outputs at each stage and comparing them with the outputs in the truth table. Any discrepancy in the functioning of the IC results in a fail indication, displays the faulty and good gates on the LCD. The testing procedure is accomplished with the help of keys present on the main board.

This project has been tested with most commonly used digital IC's, mainly belonging to the 74TTL series. Digital IC tester tests various types of IC's like OR, XOR, NAND, AND, NOT, NOR, XNOR GATES and also FULL ADDER, MULTIPLEXER, SHIFT REGISTER.

A special thanks to Sunil Raina, Piyush Sonawane and Parimal Sikchi for sharing their work with us.

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.

I want to thank Kiran Gowle (kirangowle) for submitting this project. I am sure his contribution will help many others on this website. If you have any queries regarding this project, Please feel free to post in forum.
