The project presented here is based on world’s most powerful microco-ntroller based on intel’s mcs-51 family , generally known as intel-8051. We have used its derivative atmel-89c2051

Line Follower

SUMMARY:We have fixed two light sensors on fore side on the robo. The principle of sensors is that black colour will normally observe the light where other colours will normally reflects the

lights light source is fixed down ward Ld1 ,a white led reflected light will fall on the ldr if the light is more the resistance of the ldr is normally low and transistor remains in cutoff state

When the robo moves on the black road , the light reflected is less and the l dr resistance is increased, vr1 forms a potential driver along with ldr due to increase in resistance the base voltage on t1 will rise to conduction level and transister will go into on (conduction)state.

Resulting it’s collector which was getting high logic from the default microcontroller pin will become low. This low logic detection confirms that the robo is on the black road if the robo is our of the black road this logic will become high and it indicates off-road. Depending upon the left or right sensor robo will move towards right or left direction in order to stay on road out put from both the sensors should be low when the robo is on the road.

Based on the input of the sensors will move in forward direction left or right direction

We have also added head light, back light.. These lights automatically comes on while robo is in movement.Pin no 16 of u1 is connected to pino 5 of u2 out put of u2 at pin no 16 enable the motor driver ic pin no 1 and 9 on u3 .pin no 17 and 18 of microcontroller u1 controls the motor m1.pin no 14 and pin no 15 of u1 controls the motor m2 when both pins high or low nothing happens motor will not turn

Construction: Solder all the parts provided in the kit properly. First connect the jumper wires(links) before you solder the ic sockets. Do not solder integrated circuits directly on the circuit board , it may damage the ic since you my not be experienced soldering person. So solder the ic sockets first on the circuit board. Solder smaller components first like resistance and disk capacitors, assemble the complete kit one by one. Please make sure that there are no short circuits left on to the circuit board. Check the power supply at all the sockets mounted on circuit board it should be 5 to 6.5v dc.

GSM Mobile Controlled PC (Computer)

GSM based Personal computer control system is a Micro Controller based control system which is interfaced to the computer through a wireless GSM network. It is a application dependent project which requires a specially designed application program in the hosting system i.e. our personal computer which has to be controlled should be installed with a application program such as Windows/UNIX environment so that it can understand the commands received from the controller unit. Here we are going to interface our Microcontroller based hardware module to the Operating system of the Personal Computer, so that we can control the operations of few applications such as windows media player, notepad etc through mobile phone or modem from any where in the world.The major building blocks of this project are:-

• Regulated Power Supply
• GSM Modem/Mobile
• Microcontroller Unit
• Personal Computer
• PC drivers

GSM based Device Monitoring and Control System

The purpose of this project is to monitor and control electrical devices (Analog and Digital) remotely using GSM modem/phone. The GSM modem provides the communication mechanism between the user and the microcontroller system by means of SMS messages.
User can control multiple electrical devices by sending suitably formatted SMS message to the microcontroller based control system. These SMS commands are interpreted by microcontroller system and are validated. If the SMS command received is valid then it takes the necessary action to control the said devices.
This system also continuously monitors the status of devices connected to it. If the status of any critical device changes from ON to OFF or vice versa, then microcontroller based system automatically sends the SMS alerts back to user. After completion of the command implementation this system sends the confirmation messages back to the calling user. The major building blocks of this project are:

1. Microcontroller based control system with regulated power supply.
2. GSM Modem/phone.
3. Digital and Analog sensors and controlled devices.

GPS Data Logger into MMC/SD Memory Card

lobal Positioning System (GPS) has been used in various commercial applications including transportation, navigation and vehicle position tracking, which when coupled with external memory stick the technology can help track the complete journey of any vehicle or moving objects like human or animals.This project aims to construct a vehicle position logging system using GPS and SD/MMC (Multi Media Card). The system comprises two modules. The GPS data receiver module gets the data from GPS receiver and processes it. The data storage module consists of an interface circuit between the GPS and the MMC card. This module transmits the data to the MMC card that can be displayed on a computerized map.The requested data is then superimposed on the Google Earth map, which covers major cities and towns within India and abroad.

The project works satisfactorily in real time, can locate the vehicle travel locations in the form of longitude, latitude with the margin of error not more than 6 meters from the actual location. This system also logs the information like date, time and speed information of the vehicle.
The major building blocks of this project are:

1. Microcontroller based control system with regulated power supply.
2. GPS receiver.
3. Memory Stick (MMC) interfacing system.

GSM Based Automatic Energy Meter Reading System

The purpose of this project is to remote monitoring and control of the Domestic Energy meter. This system enables the Electricity Department to read the meter readings regularly without the person visiting each house. This can be achieved by the use of microcontroller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location. This system also makes use of a GSM modem for remote monitoring and control of Energy Meter. The Microcontroller based system continuously records the readings and the live meter reading can be sent to the Electricity department on request. This system also can be used to disconnect the power supply to the house in case of non-payment of electricity bills. A dedicated GSM modem with SIM card is required for each energy meter.The major building blocks of this project are:
Microcontroller based control system with regulated power supply.

Obstacle detection Robot with Ultrasonic Sensors

Obstacle detection Robot with Ultrasonic Sensors automatically senses the presence of a obstacle in its path and deviates its path or stops its journey. The obstacle detection mechanism is managed by a ultrasonic sensor which makes uses of ultrasonic waves to find the presence of a obstacle in its path.The robot consists of an 8-bit microcontroller to communicate with the sensor and takes any action depending upon the feedback received from the ultrasonic sensor. Here the micro controller part is to control the movement of the robot as well as to read the input from the sensor unit.This also consists of few dc motors to rotate the wheels of the robot. The motor is rotated as per the direction in which the robot has to be moved, these kind of intelligent decisions are to be taken by the controller.
