Here I am going to teach you a simple circuit of 24 hour digital clock display that can also be used in 12 hour format by simply loading the corresponding clock program. You can download the hex files for both 12 hour format and 24 hour time system from the link given in this article. […]
Overview Trinket lends itself very well to building clock projects, its small and easy to hide behind a larger display. And clocks don’t need a lot of logic, this example only has maybe 20 lines of code. Adding a digital display via I2C is possible using seven segment or character-based displays (with the library code
Always the right time and date with DCF77 This project make use of a PIC16F628(A) and a DCF77 receiver from Conrad (Orderno. 64 11 38) Optional there is a possibility to connect an electronic gong on it. Click for information about DCF77 on the link underneath: The working from the DCF77 time signal Connect the output from the

In digital electronics, fan-out is defined as the number of gate inputs that the output of a single logic gate can feed. It is very important in digital systems for a single logic gate to drive other gates or devices. In this case, a buffer can be used between the logic gate and the devices
You can use a PIC microcontroller and an LED matrix to create a binary clock (or if you prefer you can wire up individual LEDs). This project uses an LED matrix block as it saves lots of wiring. So what is it ? Its an led clock that displays the time information as binary numbers…

GPS satellites and GPS Ground Segment need extremely accurate timing to allow GPS users to know their own position on the Earth. Rubidium and Cesium clock generators are extensively used and maintained to synchronize and generate the signals that our inexpensive navigator gets from the GPS satellites orbiting at 20000 Km. Many commercial systems use

In this post I’m going to show you how to interface an I2C Real Time Clock – RTC with PIC microcontroller. Only a basic hardware configuration and a communication protocol are presented here. I’m planning to extend it to a more advanced design in a near future. Although PCF8573 was used a similar IC’s like
The Multimeter Clock consists of three multimeters, the first meter displays hours, the second displays minutes and the last displays seconds. A 16F628A PIC microcontroller keeps track of time and outputs a calculated current to each meter to display the current time. Get your own Multimeter Clock Kit here. See Multimeter Clock project page here.
An eight pin Microchip PIC microcontroller is programmed to operate from a 32768 Hz watch crystal and output waveforms which, when displayed on an oscilloscope, show the time in HH:MM:SS format. The screen capture shows winscope showing 12:46: … Step 1: Design the character set On an oscilloscope screen, vertical axis (up and down) corresponds
This reference design features the 8T49NS010 integrated circuit that functions as a clock synthesizer with a built-in fanout buffer and divider. By using an external clock source or a crystal, the 8T49NS010 can generate high performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise jitter, such as
