May be this DIY Project will be a great help for students in the exam times and also for office going persons.

The Alarm Carpet is a very simple electronics DIY Project. The main parts including in the Alarm Carpet DIY Project  are a controller, buzzer, seven segment displays, Alarm enabler, Alarm setting keys and of course, the battery. The Alarm Disabler section must be placed under the Alarm Carpet and the other parts can be placed anywhere according to your requirements. There are five alarm keys provided for setting the alarm in hours or minutes. Actually the Alarm/Buzzer along with two digit seven segment display will work as a timer, and when we set a particular time using the alarm keys, the Alarm starts count down and it will be displayed by the two digit seven segment display.  The buzzer starts ringing as far as the countdown completed. The Wake up Alarm buzzer stops only when the person gets up from his bed and stands upon the Alarm Carpet, since the alarm Disabler is embedded in the Wake up Alarm Carpet. If you want this as an Alarm Carpet Challenge, Place the Wake up Alarm Carpet apart from your bed and place it infront of your washbasin, so as to wake up you freshly……

The block diagram of electronics DIY project – alarm carpet is given here. There is a 5 alarm setting key, through which you can set the Alarm Time. The controller used in this electronics DIY project – alarm carpet is Pic16F883 Microcontroller, which is the heart of the wake up alarm DIY Project. A 2 digit 7 Segment Display is used for displaying the timer count down status. Also two indicators are provided for indicating the Countdown time in hours and minutes. The Alarm Disabler switch is used for disabling the buzzer. The power required for the whole wake up alarm DIY Project is provided by the battery section.
