The main scope of PC OPERATED ROBO USING WI-FI project is to control the Industrial Machines by using Wi-Fi Technology. An embedded project is a combination of hardware and software designed to perform a specific task. The main scope of this project is to develop the application for industrial automation using wire less communication as Wi-Fi embedded technology to reduce the complexity in design.

Wi-fi also known as 802.11b uses radio waves to send information at speeds of up to 11 Megabits per second over a range of up to 300 feet. When combined with a wireless access point or wireless router, it provides users with wireless high speed internet access. 

In our project we tried to demonstrate the wi-fi technology using small application. The project work includes study and design of hardware unit and software. We programmed Wi-Fi module which is interfaced to the micro-controller unit and some analog circuit which in turn drives the loads. So the complete project can be divided in to two modules i.e. Design of the user interface application and the other is the microcontroller Unit and its software which will be written in Embedded C Language.

PC controlled Robot using ZigBee network projects main idea is to develop a robot application which can control through remotely using a ZigBee network. This network is one of the widely used open source wireless network available in the market. This can be used for developing projects.

To control the direction of the robot we are using Xbee modules one as transmitter and the other as receiver. The transmitter is fixed to PC and the receiver is fixed to the robot on the other end. We send signals from PC through the Xbee (transmitter) to the receiver which is in built to the robot.

We can use this process to visually control the robot direction even though we are far away by connecting a camera in front of the robot.

Aim:The main aim of PC BASED SYNCHRONIZING AND SPEED CONTROLLING OF DC MOTOR project is to control the speed of DC motor and on/off the motor using PC.

Description:  If the voltage is varied, the motor would not be able to deliver the rated torque when operated at voltages lower than its recommended operating voltage. This problem can be over come by using PWM technique. PWM stands for pulse width modulation. The speed of the DC motor controlled by PC. This data is transferred to Micro controller serially. Here in Microcontroller  produce a square wave with variable duty cycle. The variable duty cycle in effect dictates the speed of the motor. Here the fundamental frequency of the square wave is constant for only the ON and OFF, time is appropriately manipulated. More ON time will cause the motor to run at higher speeds. As the ON time is reduced and proportionally the time is increased, the motor would slow down.

Typical 50% duty cycle: Equal On time and off time.

MMC card interface to the micro controller using SPI protocol for industrial data loggers project explains about procedure to interface pen drive like device called MMC to the micro controller. This application users SPI protocol for implementing this project. Basically MMC device is used for storing data, it can be easily connected to digital cameras to store images. This device can be connected to personal computer or laptops for transfer of data.

            In this project we are using LM35 as a temperature sensor. The Microcontroller reads the temperature data and stores it into the MMC card. This application note includes all of the necessary code for reading from and writing to an MMC card that has been formatted with a FAT file system.

Applications:

• Cellular phones
•  digital audio players
• digital cameras
•  PDAs

The aim of Safety Auto Brake System for Hill Station Vehicle Using MEMS Sensor project is to design and construction of a module used for vehicles in the hill stations. auto breaking system is used when vehicle is moving up ward direction  .  The project was divided into two phases. The First phase is to demonstrate the application of MEMS. The second phase of the project attempts controlling motors.

I2C protocol is used for interfacing MEMS sensors with micro controller, Micro controller main functionality is to receive signals for sensors and process information by taking desired decision. Applications which use this technology are refrigerators, operation theaters and microwaves.

This paper will explain the detailed information on Motion Operated Scrolling Display Using Dual Axis MEMS Accelerometer and LCD Display A motion operated scrolling display system including a motion sensor responsive to motion of a device and providing a signal corresponding to movement of the device.

A database including stored data values corresponding to predetermined motion of the device; motion sensors will interact with electronic circuit to analyze motion sensor signals with the information contained in the database and, in response, to provide an output signal for performing at least one display angle of a pres elected set of display angles when the comparison reveals that the device has moved in a way which corresponds to the stored data values. And it scrolls the displayed data according to the angle.
