Logic rather than any programming based element. On building a digital clock with simple gates, flip-flops and counters with sequential Very common and efficient option for displaying a decimal value. Giving a clock signal to the next counter when it resets.
Work in a similar fashion by receiving a clock signal from the previous counter and The counter triggers the counter next to it when it resets. Thisĭriver decodes the binary input to decimal and sends it to the seven segment display. Given to the decade counter which provides binary output to the decoder driver. The main clock signal having 1 Hertz frequency is Digital clock has aĬounter that receives a clock signal from any source and increases the numberĪccording to the clock signal. With the help of counters and decoders, a digital clock toĭisplay time in hours, minutes and seconds can be constructed. Time digitally, in contrast to an analog clock, where the time is indicated by the Will meet you guys soon in the next post.The aim of the project is to design a twelve hour Digital Clock that displays the
Mini digital clock code#

Now use the below code and get your hex file.First of all, design a circuit as shown in below figure:.:) Interrupt Based Digital Clock with 8051 Microcontroller So, let's get started with Interrupt based Digital clock with 8051 Microcontroller. The complete simulation along with code is given at the end of this post but my suggestion is to design it on your own so that you get most of it. You can also implement this digital clock with any other microcontroller like Arduino or PIC Microcontroller but today we are gonna implement it on 8051 Microcontroller.
This clock will be displayed on LCD so if you are not familiar with LCD then must read Interfacing of LCD with 8051 Microcontroller. In today's post, I am gonna design a digital clock which will increment after every one second and we will calculate this one second increment using timer interrupt. So, before going into details of this post, you must read that timer post as I am gonna use these timer interrupts in today's post.Īfter reading this post, you will also get the skilled hand on timer interrupt and can understand them more easily. Using these timers we can easily generate interrupts. We have seen in that post that we can use two timers in 8051 Microcontroller which are Timer0 and Timer1.
Mini digital clock how to#
In the previous post, I have explained in detail How to use Timer Interrupt in 8051 Microcontroller. In today's post, I am going to share Interrupt based Digital clock with 8051 Microcontroller. Hello friends, hope you all are fine and having fun with your lives.
