The time will be display with 3 seven segment display, this can be used as a 1 for minute and 2 for seconds or all display for minutes only. The buzzer will alarm every after thirty minutes. This is to jog the memory of the examinees, on how much time is left. When the time period is finished, another beep from the buzzer would be heard to remind the examiner and the examinees that the exam is completed. Summary and Conclusion

Whether you have a day to prepare for an exam or a week to cram and study, having a countdown timer during examinations can help students be run by once more of how much time is merely left. Seeing the timer approaches to zero activate a student’s adrenaline to haste which aids to finish the work he/ she is doing more hurriedly and more .NET acoustically. Being unconscious of the time left might put anyone to a comfort zone, not performing his/her task quickly, not knowing that time is running out; or it might put any person to a cram condition, doing his/her task too hurriedly without concentration, not owing that there is still time left.

Having a timer, time management will definitely be better. This project helps not only for the students but also for proctors as well. We conclude that this project indeed suitable for Computer Engineering students, especially to those taking up Circuits I and Computer Systems Organization. By accomplishing this project, we have now seen as exact useful of our lessons. Resume Its After we conducted a 90, 180 and 240 minute test to our timer we come across with a particular conflict regarding its display. The more the number we set to our timer the more it blaze its ground in the display.

As a students and a learners at the same time in this case we don’t know how to fix this kind of engagement at this time because we’re not that exposed in this matter but we’re thinking a prodigious solution with this kind of problem and hopefully to fix and improve our device. Recommendation Though this project predominantly emphases on examination timer as its title implies, modification of this project can lead to other applications as well. A parking meter for instance. Placing in a coin starts the internal timer counting down from an initial preset point.

When the time has over and done, the “expired” flag is bespattered. One type Of timer used broadly in industry is the process control timer. Another example, when a product is completed, it may need to be warmth preserved for a specific length of time. In a programmed manufacturing system, the process control timer regulates the amount of time that the item is heated. In some applications, such as integrated circuit engineering, the timing process can be critical for proper action. Process intro timers are also used in many diverse types of laboratory atmospheres.

Calibration laboratories use timers to calibrate units such as radiation detectors, where they adjust the quantity of time the detector is unprotected to the radiation source. Any uncertainty in the time of exposure directly influences the vagueness of the detector calibration. Timers are also used in the medical field. For example, medical test centers and research rooms practice a process control timers when specimen cultures are grown. Hospitals use timers to normalize the amount of medication given to patients intravenously.

Many sorts of timing devices are used in every day money- making applications. Parking meters, automatic car wash accommodations, taxicab meters, and commercial parking lots are examples of objects that either charge a certain amount for a quantified period or be responsible for a certain period of service for a specified amount. For further studies or any modification on how the timer should be used in a coordination, the advocates suggest that this project will serve as a backbone for further studies that is related to timing circuits.
