Arduino Clock using Standard Clock Display

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 a real time clock (RTC) * Using a basic clock display - the type you see on most ...

Make an Atom Synchronised Clock from a 1950’s Slave Dial using Arduino

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 sent by a centralised master time-keeping mechanism. They were often used railway stations ...

Tutorial 16: Arduino Clock

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 used to back up the time and date settings in the real time clock chip so that the time and date are not lost if the ...

Learning Sequential Logic Design for a Digital Clock

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 I have seen) use the 7490 counter (I have used 7493 but I will show w ...

Arduino DS1307 Clock

1) Introduction and Images Hello friends, today I am going to build a Digital Clock using Arduino UNO and famous DS1307 Real Time Clock IC. Before we begin, here are some images of the completed project. You can find the YouTube video at the bottom of the page 2) DS1307 RTC IC DS1307 is a low power serial real time clock with full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The RTC p ...

LED Sunrise Alarm Clock with Customizable Song Alarm using arduino

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 but still being tired, not being able to get out of bed, depression, and even some physical problems ...

Let’s make an Arduino real time clock shield

Today we are going to make a real time clock Arduino shield. Doing so will give you a simple way of adding … real time capability to your projects such as time, date, alarms and so on. We will use the inexpensive Maxim DS1307 real-time clock IC. First of all, we need create our circuit diagram. Thankfully the Maxim DS1307 data sheet [pdf] has this basics laid out on page one. From examining a DS1307 board u ...

The Wordclock Grew Up! using arduino

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, It got better. I have discovered how to cut Vinyl stencils, and have been experimenting with Pe ...

Build a network clock (NCLK) with Microduino-RTC

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.

An Open Source, hackable Digital Clock

Andrew O’Malley, an amazingly creative maker, created this fanstastic Open Source Arduino-based clock that can display the time in many different ways: if not enough, one can also add his own personal animation. Compared to other clocks based on Arduino, this one has two distinctive features: a single board with the ATmega 328P chip plus the RTC (not a shield) and a led matrix display (16 x 24 pixels) based ...

Alarm Clock with Tetris to Prove You’re Awake using Arduino

This is an Arduino powered alarm clock that after hitting snooze twice the alarm will not cancel until the user has cleared 4 lines in the game Tetris. You physically turn the clock sideways, so the screen is vertical, to play Tetris.  It's never fun to wake up in the morning but playing a little Tetris is at least somewhat enjoyable and quite effective. Feel free to vote for me in the microcontriller conte ...
