Homemade Digital Clock

A 24 hour based clock based on dual decade counters, AND gates, OR gates, BCD to Decimal Converters, and a crystal oscillator. No micro controllers here. This instructable contains PCB art so you can easily make your own. Quantity is in parentheses. Item number at Digikey.com is in brackets. 6 74HC390 Dual Decade Counters 568-1442-5-ND

As the time base had switched from mechanical to electrical, the time display had to follow suit. Display devices called 7 segment displays were designed to allow the time to be shown numerically. While many digital clocks are available commercially, you can also build your own from components. Follow these tips to learn how to make a digital

However, this DIY digital clock kit provided by them is exceptional in quality and performance. With this, you have the option to change the time range to 24-hour or 12-hour. This clock kit also has different beneficial features that include time correction, time-temperature cycle display, time-day-week display and others.

The clock we are going to make will display the hour, minute, and second in both the 12-hour and 24-hour format. We will also include a feature to adjust the time, so you don't have to make changes manually. Here is the step by step guide to make a digital clock using Arduino and 162 LCD display. Step 1 Gather the Parts of Digital Clock

The clock is made of six seven segment displays which make up the display. Each digit made of seven segments and every segment made of 3 LEDs in parallel. So a simple calculation gives that there are 21 LEDs in each seven segment display. And all six digits take 126 LEDs.

The clock features a frame made from 18mm thick spruce wood, which needs to be cut to size first. I started by cutting the board to a square shape of 300300 mm. Next, I marked the inner circle with a diameter of 220 mm and an evenly spaced octagonal pattern with a side length of approximately 124 mm. Using a jigsaw, cutting the board to its

This digital clock has just two main components, the Arduino and LCD display. The Arduino is the brain of the clock, which does mathematical and logical functions to updates the clock every second. And that is the main reason why I started this website homemade-circuits.com, to share different types of circuit ideas..

Overall, the digital clock schematic provides a clear understanding of how the different components are connected and how they work together to display the time accurately. It serves as a foundation for designing and building a simple digital clock circuit, which can be a fun DIY electronics project for beginners and enthusiasts alike.
