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

This project is an extention to previously uploaded "GSM Controlled Robot". Earlier project was only designed to be controlled using a mobile or GSM device whereas this project extends the control capabilities to custom designed RF Remote and A glove with Accelerometer.



This project is devided into two sections
1. Control/Encoder unit
2. Robot Unit

Control unit uses 433Mhz RF modules for sending control data to robot. Control unit receives data from either remote or an accelerometer module. Robot unit is actually the receving device which can receive data from either gsm device or RF recevier. Both RF reciever and GSM device send same kind of signals to control motors.

Control/encoder unit uses 8051 controller and its code is written in assembly whereas Robot unit uses AVR microcontroller, its source is written in C language. If you have already built the old GSM controlled robot then upgrading to this version of robot will not be difficult at all.

I have also added original project report came with GSM controlled robot, You can add more information in this project report to complete final report.

Here are working videos of project:

Hi Friends, Its been a long time since I've been to website. But There were few main things that I was suppose to do a long time back. Here is a new year surprise for you all. Viktor has share another project with us a great design with practical use. An 8051 based Solar tracker with source written in assembly language. Viktor explains basic operation of this project.

PRINCIPLE OF OPERATION
The circuit comprises of three sections:
  1. light controlled circuit
  2. counter for timer
  3. switching circuit


1. Light controlled circuit:

This particular circuit controls other circuits. It puts the other circuit on or off depending the nature of the day. It comprises of LDR and transistor representation of smith trigger configured using two npn transistor(BC377) such that when there is a small potential difference across the LDR and variable resistor, The relay will be triggered to switch on other circuit. This circuit monitors day and night. The main function of this monitor is put off the device at night and turn it on in the mornining again.

2. counter for timer:
Since sun start from the east at 6:45am and set at exertly 12:45pm, the light controller circuit put on the whole circuit automatically making the timer to initialize its 6hrs counting sequence.

3. switching circuit:
This circuit is mainly used to control the direction of panel using a DC Actuator motor. Microcontroller AT89C2051 gets input from east and west Light control circuit and adjust panel to face sun direction.

Type of motor used:
24-36v d.c Actuator from super jack used in tv satalite dish polar adjustment
