There are many digital alarm clocks that available in the market, but most of the digital alarm clocks are only have a single time local time feature, where you’re going to spend more money out from your wallet, if you want to have dual time digital alarm clock!

Well, if you choose not to buy the digital alarm clock, then would you interested to develop a dual time digital alarm clock here?

The microcontroller that you’re about to use is the PIC16F873A, where this PIC used is a 28 pin high performance RISC microcontroller from Microchip Inc and it having a 4K byte program memory. One of the main reasons why you should use PIC16F873A, because it is a flash based and a member of PIC16F873A family of low cost, CMOS, fully static, 8 bit microcontroller. The best part about this PIC is it requires less external components, hence it can reduce great sum of cost and total power consumption.

By the way, this Dual time digital alarm clock can easily be set according to your own need, in either standard time or GMT time zone! Furthermore, it has a leap year correction, which is valid up to year 2100 too!
