This is a fun speaker timer I made for some upcoming conferences. It uses a 4-digit charlieplexed LED (pseudo 7-segment) display and is driven by a AVR ATMega328 or an Arduino. It allows a default time to be set, can be paused, and will put out 5 Volts on several IO lines when 10, 5, […]

Hello everyone; I was looking for this project for a long time. Finally I it it together with a lot of effort. For this project you will need: [box color=”#985D00″ bg=”#FFF8CB” font=”verdana” fontsize=”14 ” radius=”20 ” border=”#985D12″ float=”right” head=”Major Components in Project” headbg=”#FFEB70″ headcolor=”#985D00″] 1- Arduino Uno ($30 from Radio Shack) 2- RTC DS1307 (like

This is a relatively simple clock to build, in terms of the hardware required and in terms of hooking up all the wires. The complexity lies in the software, which I’ve conveniently included as part of this instructable 🙂 This instructable illustrates a few things: * Keeping relatively accurate time on an Arduino without using

One day while exploring the bric-a-brac at the markets, I stumbled across an old, Bakelite slave dial from the 1950’s. Slave Dials are clock movements without the actual time keeping circuit. All they contain is the mechanism to drive the hour and minute hands, which can be advanced by an electric pulse. This pulse is

In this tutorial, the Arduino displays the time and date on a LCD (optional) and in the Arduino IDE serial monitor window. A PCF8563 real time clock (RTC) IC is used to generate the time and date. The time and date can be set using the Arduino serial monitor window. An optional battery can be

This instructable is for two purposes 1) to understand and learn the fundamentals of sequential logic 2) use that knowledge to create a digital clock. Digital clocks have been built by countless electronics hobbyists over the world. So why have I chosen to implement that? Well usually clock circuits available on the internet (all circuits

My Motivation This winter my girlfriend had a lot of trouble waking up in the morning and seemed to be suffering from SAD (Seasonal Affective Disorder). I even notice how much harder it is to wake up in the winter since the sun hasn’t come up yet. Symptoms of severe SAD can include irritability, oversleeping

Well, It had to happen. I first published my WordClock project in September 2009. It was a Microchip PIC based clock, using a PIC16F877A microprocessor. In the last year and a half, I have been constantly improving it, and have adapted it to the Arduino, and even designed an updated controller board for it. Well,

The resolvent of clock synchronization over internet. by PKJ, The web−based clock management system allows you to monitor clock status from wherever they are and centrally change settings. and this small device is built with PoE technology, thus IP clocks get their time, data and power from the same network that supports your other IP endpoints.
