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.

AIM

Rc5 IR Based Remote Device Switching main aim is to develop a micro controller project which can handle home devices using a remote control which runs on IR frequency. This frequency is mainly used as T.V remote.

DESCRIPTION: 

This project describes to control the devices from some distance using RF data communication. Here we are transmitting a signal from remote control by pressing a button. Then the micro controller does the corresponding operation like switching ON and OFF devices and to control the AC load through TRIAC circuit and here micro controller as a driver. TRIAC is a tri-state AC switch, it is nothing but a switch which can conduct in both the ways and also triac can up to 600V AC. Advantages are we operate the devices at some distance, power saving, easy to operate. Applications are in hotel environments, office environments etc.

Aim:

Aim of  IR Based Distance Measurement System project is to determine the distance  of an Object, using IR range finder sensor.

Description:

IR Range finder consists an IR LED and IR detector circuit, in which IR LED emits IR, pulses continuously when power up. If any obstacle is in between its path then pulses revert back and hit the IR detector. This detector directly gives voltage output. With respective to the distance of object the output voltage may vary linearly. 

          This IR Range finder Sensor is directly connected to microcontroller through ADC. If any obstacle is in between its line of sight then IR pulses coming from IR transmitter will reflect back at object and hit the IR detector. According to that it produce voltage output by calculating its time of flight. So that microcontroller determines the distance of object with respect to that voltage output coming from sensor.
