On the desktop computer my computer icon was right clicked and manage option was chosen and further the device manager option was selected and then the ports option was clicked which depicted the communication port as port 1 and the USB to serial port as port 3. The keil µ-vision 4 software was used to write the C program for the display of text message “DYNAMIC PERSON MOYEED ABRAR” on the LCDscreen located on the ARM-09 NXP LPC2148 Microcontroller board . The following sequence of steps was followed in order to get the desired output.
According to the code written, every time an obstacle is detected and its position is displayed on the LCDscreen, the whole screen is erased. Due to this the screen appears as if it flickers frequently. It was one of the constraints of this module. There are possibilities of cross talk when using multiple ultrasonic sensors. The ultrasonic sensors may read the signal from other sensor hence producing a wrong output .
After done with placing command on the flowchart, push button on top of the flowchart is pressed to answer the question. The actual output is then will display on the TFT LCD. Green LED will light up if the user gets the correct answer and buzzer will produce a tone with melody while the red LED will light up if the user provides wrong answer and buzz sound will be produced. In the meantime, the LCDscreen will display the result from answering the question whether it is correct or wrong and mark is given only for the correct answer. Lastly, an instruction is given in last row of the same display for the result and mark obtained where it ask the user to press ‘#’ button to proceed to the next question. This project consists of 4 questions and the same process is repeated for the entire questions except command us.

automated resistor sorting machine that can function as a device for measuring and sorting the resistors that are used in laboratories with minimum human interference and increased accuracy. It appealed to us because we felt it would give us a chance to combine different fields of engineering: mechanical, electronics and computer. Essentially, herein, the concept voltage drop across a resistor is bootstrapped with the mechanical movements of servos to produce the required output. Our project provides two functions, namely- sorting and measuring of resistors which can be selected using an LCDscreen and a mobile app. It accepts resistors, and sorts them into predefined bins or measures, displays the value and returns it to the user.
In our proposed work we use laser light module (transmitter and receiver) for the arrival of train is a new concept for our project and count down process and message printing on a lcdscreen make our project more fruitful to common people. Another feature of our project is live telecasting of the arrival of the train on a screen as a sender and receiver processing using Arducam mini camera.So people can see the actual position of the train from the railway gate. This feature can aware people and prevent accidents and the timer on the lcdscreen will prevent the sudden fall down of the railway gate on the veichle or car or human beings.Prevention of an accident can be solved in such a way that when the train detects the presence of people in front of the train using PIR sensor the speed of the train gradually decreases and the speed controller will help to reduce the speed and finally the train will stop.

display the working of that line. Microcontroller circuit is fed by a +5 V supply and the ports are assigned their respective operations as shown in the pin diagram. The unused ports such as TX RX are not used in the project. The relay senses the type of fault and through the program loaded in the microcontroller the result is displayed on the LCDscreen. The ports as assigned their respective functions works accordingly and gives a output on the LCDscreen which is a 16 port device whose working is dependent upon the interfacing done between the microcontroller and LCD. LCD Microcontroller interfacing is being done and hence depending upon the program loaded in the microcontroller the output is seen on the LCDscreen. Different phase sensing ports as assigned in the port diagram senses the failure and gives the fault of phase failure. Same is the case with the Earth and UV detection faults. Individual Faults are seen as below with display on the LCDscreen.
The device is an automated egg incubator. The parameters that will be automated includes: the temperature regulation and the egg rack rotation. Both the ambient temperature and humidity will be monitored by a DHT-11 Temperature and Humidity Sensor. Two racks with a capacity of thirty-five eggs each will be attached to the egg turner. This will be powered by a Direct Current (DC) Motor. The current ambient temperature and humidity will be displayed in a Liquid Crystal Display (LCD) screen as well as through text using a Global System for Mobile Communications (GSM) Module via Short Message Service (SMS).
This project will focus primarily on circuit construction such as PIC16F877A as the microcontroller, LED as power indicator, 4x4 keypad for keying in password, ICSP (In Circuit Serial Programming) for loading program, and push button as input for PIC microcontroller. Second, this project will also focus on LCDscreen display which is used to display words and password symbols. Finally, relay and buzzer will function as output for this system which can be applied to any daily application such as door lock.
To overcome these safety problems with existing LCDscreen, we propose a concept that combines human voice recognition technology with service details i.e. if driver is busy in driving then he can just click on an icon on LCDscreen and there after he will get to know the service details of various parts of vehicle with human voice and there is no need for him to look at the screen. This will definitely help in decreasing the number of accidents. Currently in the proposed idea, the driver needs to give the date on which service has been carried out as a input to the system. Further in the future there is a scope that, the driver intervention can be completely removed by using some other means of automation.
headache (42.66%),diminution of vision for distance (34%) and watering (32%) among the asthenopic complaints in the com- puter workers of our university. A high prevalence of asthenopic complaints (46.3%) in the computer operators was also reported in a similar study . A study which was performed on 385 bank workers of Italy reported the prevalence of such ocular com- plaints to be 31.9% . Another study which was done in Spain found this prevalence to be as high as 68.5% . In our study, the major ocular complaints which were reported in the descend- ing order were eyestrain, headache, diminution of vision for dis- tance, watering, redness, itching, burning and double vision. In our study, the female subjects used computers for lesser time periods than the males, as well as, most of them maintained a proper viewing distance from the computer screen, but we did not find any significant association with the age and gender of the subjects with these complaints.Such ocular complaints were correlated with the age and gender of the subjects in one such study . The visual symptoms scores in the visual display termi- nal operators were found to be higher among the females than among the males in a Japanese study. However, they did not find any difference with respect to the age . While considering the duration of the computer use, the review of literature revealed mixed pictures as far as the occurrence of the ocular complaints was concerned. One of the studies found a significant difference in such complaints and in the daily hours of the visual display ter- minal work between the workers who worked less than 6 hrs daily and those who worked more than 6 hours daily .
Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to avoid locations where excessive heat, humidity, dust and vibration are expected. Always keep the AR8200 free from dust and moisture. Use a soft, dry cloth to gently wipe the set clean, never use abrasive cleaners or organic solvents which may damage certain parts. Treat the AR8200 with care, avoid spillage or leakage of liquids into the receiver and a.c. charger. Special care should be taken to avoid liquid entering around the controls, through the speaker grille or via the connection jacks.
