Digital Clock Using Microcontroller 89C52/89S52

Posted on Feb 7, 2014

Are you a beginner in micro controller projects and are you stuck where to start from if yes, then this is one of the simplest mini projects that you can start from. This mini project will give you a clear understanding of programming your micro controller. we sometimes look at our watch and wonder ` how does this thing work`. Well, in this digita

l clock project, you will gain some insight on how micro controller can be used to make it work as a Digital Clock. This project has been done in proteus software. If you are new to proteus software, the tutorials given below may get you started with the software. note:if you are familiar with proteus you can skip this part. The programming of the microcontroller is done using keil compiler. port 2 of 89C52 is used as the output port. whereas port 1 is used as the input port. when P1_4 is grounded the 12 hr mode is activated and when P1_5 is grounded the 24 hr mode is activated. In the schematic diagram P1_5 is grounded so the 24hr mode is activated. it is as shown below
