Clock

A clock is an instrument used to measure, keep, and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia.

ArClock - a Smart Display Wrapped in Real Wood

“ArClock is my updating of the “LED clock inside a block of wood” idea. It’s a pretty simple build and the result is eye-catching but tasteful (depending on how it’s configured!). It’s built around a WiFi-enabled microcontroller …

Digital Clock But Without a Microcontroller

“A digital clock completely built from scratch without any coding or microcontroller. Just by using only 74xx and 40xx series digital IC. It’s pretty easy to build circuits with a microcontroller but we totally forget the tons of work …

7 Segment Clock Version 2

“Hello! After a request from Instructables user regarding availability of 12h format, i took advantage to make substancial changes to the original project. During using of the version 1 i felt the need to make a stand-alone version, so I …

How to Make NTP Clock Using ESP8266 and 74HC595

“The main controller in this project is the ESP8266 which is contained in the Wemos D1 Mini Module. With integrated WiFi in it, it allows many things to be done. One of them is making a clock using NTP (Network …

Yet another dot matrix clock

“NTP synchronized dot matrix clock showing temperatures and humidity.. Optionally the time source can be GPS. That is what some readers may think, what? Another dot matrix clock? In order to combine inside/outside thermometers with a nice and precise …

Arduino Nano Project Displaying Clock, Calendar and Internal and External Temperatures

“This project is about building your own micro controller hardware and software. The micro controller is the Arduino Nano. The development software platform is either PlatformIO or Arduino development studio. After years of programming mainframes, mini-computers, and desktop computers I …

Network Connected RGB Matrix Clock

“Build a beautiful, modern digital clock with a retro flair using CircuitPython, Metro M4 Airlift, RGB Matrix shield, and a 64 x 32 LED RGB pixel matrix display. WiFi connectivity with the Metro M4 Airlift keeps your clock in sync …

LEDura - Analog LED Clock

“After a long time of just making various project I decided to make an instructable myself. For the first one, I will guide you through process of making your own analog clock made with awesome addressable LED ring. The inner …

Project  Metaclock

Metaclock

“Some time ago I saw a Tweet from the arduino official account talking about an amazing project called “clockception!”, the project seems to be a digital clock created using 24 analog clocks! The video run for a few seconds and …

“Connect” to an atomic clock in space! GPS, DCF77

“This project is a clock with radio receivers which can receive the exact time from the GPS satellites or from the DCF77 transmitter. This project is a clock with radio receivers which can receive the exact date and time from …
