Honestly, this is not a good habit, as it not only will turn you into an irresponsible person, but you’re also risking other people life, when you driving recklessly on the road!

For permanently solve up the above problem, what you have to do here is create a PIC-based alarm clock. You must be wondered, “Why should I build this stuff?” Well, please calm down and listen it patiently. This PIC-based alarm clock is an amazing clock, where you can programmed it to play a very loud and annoying tune through a speaker (This will keep you awake for sure!).

Beside that, it has many other useful features such as:

• Timekeeping method by using the PIC’s timer 0 interrupt;
• 4×20 hd44780 compatible backlit LCD, where it can display the time in big number;
• Alarm sound tune (It uses the PWM to control it);
• Computer interface (This is for synchronizing time, especially on web);
• The battery backup!

You can be either love it or hate it, as this PIC-based alarm clock can produce a very loud voice. Hence, it’s not suitable for those that have heart related diseases (Especially heart attack).
