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.

Our robot expert Gaurav Khadasane has come up with another innovative way to control a robot. He is controlling his robot from an android phone (with a Android GUI application) over bluetooth. Project uses our favourite 8051 microcontroller and HC-05 bluetooth module.
In this project 8051 and bluetooth module are communicating over uart @9600bps. Bluetooth module HC-05 is controlled via simple AT commands. This module comes in SMD package and works on 3.3v power supply. The BT module is a SPP supported profile so it can be connected easily to any controller or embedded device. In this profile the data sent and receive to module directly comes on the RX pin of microcontroller. It becomes really easy to make your device bluetooth compatible.
L293D H-Bridge motor driver are used to control two DC motors. A readymade compact size chassis is used to avoid the chassis assembly comlexities The chassis contains 2 decks the lower is used for BO motors fitting the upper is used as a battery stack. On top plate the controller board is mounted by screw fitting.
Finally the Android application, You can get Bluecontrol app from Google Play
Here is a working video of the project
If you have any doubts or comments Please use forum... Enjoy bulding robots

Hello I worked on a project related to Wireless Electricity theft detection using GSM during my bachelors. I used Nokia 6230 for sending sms using AT commands. I chose to work with SMS text mode. The microcontroller I used was PIC16F877A and its software coding done through PIC Basic Pro. Unfortunately, I lost my account password and do not have coding for generation sms using AT commands. I need that coding. Can some one help me to provide complete Pic Basic Pro code. In which step by step guidance is given so that I can understand easily. Regards,
