The main objective of the project is designing a programmable sequential switching of any load using embedded system based microcontroller concept. It uses microcontroller from 8051 family which is of 8-bit. The development of this application requires the configuration of microcontroller architecture that is the selection of the machines, and writing debugging of the application program. In this project, the clock plays an important role, where it is used in the following mode i.e., the set mode, auto mode and manual mode for controlling different machines. In set mode, through the digital clock the machinery will run based on/off and on time where as in auto mode they will run by default settings and finally in the manual mode the real-time systems used extensively in industrial control applications can run depending on the user’s need and flexibility. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no: 17 In this project, a generic real-time wireless communication system is designed and developed for short and long term remote patient monitoring applying appropriate protocol. The primary function of this system is to monitor the temperature of a patient’s body. The data collected by the digital temperature sensor is sent to the Microcontroller. The Microcontroller transmits the data over the air by RF (radio frequency). At the receiving end a receiver is used to receive the data and it decodes and feeds it to the Microcontroller, which is then displayed over the LCD display.

Model no : 18A The display unit, which is used to display the results of corresponding temperature of a nuclear plant and to generate a warning signal in the event of rising temperature beyond limits as set. Here the controller continuously polls the temperature with certain regular time intervals and displays over the 7_segment display unit for the Microcontroller to enable the whole operation by executing the program. The temperature readings observed by the microcontroller through temperature sensor are compared with the programmed temperature value to in turn operate the relay that switches on a warning device. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no: 19 This application is used for office automation system to save energy. 555 timer driven 38 KHz signal from IR LED gets interrupted on to the IR receiver to sense the person entering as well as exiting which is fed to a 555 timer. The output of 555 timer is fed to the Microcontroller for analyzing and control purpose. The data obtained from microcontroller is given to the 7-segment display unit which displays the number of persons entering, and exiting. This project includes TSOP 1738 IR sensor for detecting purpose. A relay is used to control any load for alert through its ‘NO’ contacts. It is interfaced with microcontroller through a relay driver. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no: 23 The outline of the project is that the text message typed using a computer keyboard attached to a microcontroller to be sent, is encrypted by using an appropriate program with LCD display and then the encrypted message is transmitted through wireless using Radio frequency transmitting Module. At the receiver end the signal is received by the RF receiver module and the analog signal is converted to digital form. It is fed to another Microcontroller where it is decrypted by the program and the message is then displayed over the receiver LCD display. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier.

The front of the car is fitted with an array of two pair of photo sensors, comprising of one IR transmitter and a photo diode in each which allows the car to detect a black path as well as any turns in the path. Colors that reflect light, such as white, produces a reflected output from the sensors whereas black color that absorbs would output low for the base drive of a pair of Darlington pair of transistors. We provide a path by pasting a black tape on a white floor. The reflected light is possible only when it is in path. Once it goes out of track/line the reflection stops and the corresponding transistor is deprived of base drive so one of the motor stops while the other continues to run to bring back the robot on the track. By reading the outputs from each of the two sensors, Darlington pair of transistors is biased. Two DC motors are connected to the collector of the transistor TIP122. The motors are able to turn the steering left or right, depending on what logic signal the sensor sends. For more info visit *******www.efxkits****; *******www.facebook****/edgefx

Model no: 33A Automatic college bell system for indicating the completion of period is a reliable circuit that takes over the manual task of switch on/off the college bell with respect to time. It has an Inbuilt Real Time Clock (RTC) which tracks the Real Time. When this time equals to the programmed ‘ON’ time, then the corresponding Relay for the device is switched ON and then OFF as per the ‘OFF’ time that finally switches the load ON or OFF. Multiple ON/OFF times entry is the biggest advantage with this project. Matrix keypad helps entering the time while relays used with relay drivers for the loads. The complete circuit has its on-board power supply. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
