Arduino GPS Clock

There are many GPS satellites around the Earth which are used to provide the exact location of any place. Along with the location coordinates (Latitude and Longitude), it also provide other data like time, date, altitude, direction tracking angle etc. We have already learned to read this GPS data from Satellite using Arduino. So we are going to make a GPS clock using the ‘Time and Date’ data from the GPS sa ...

Hard Disk Clock (HDD Clock with Arduino Uno)

This is a fun project that can be done easily and also cheaply. In this instructable we will explain step by step how to make this beautiful POV clock. Used material: Arduino Uno, RTC modul, ULN 2003, IR diode and IR transistor (used like a sensor, more details in next steps) 4 pushbuttons (for controling the clock) TSOP4838 (allows us to control the clock with remote controler) Temperature sensor (DS18B20) ...

Fun Hackable Speaker Timer

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, 1, and 1 minutes are remaining.  This allows for some fun (say firing up a NERF rocket launcher as you get closer to quitti ...

Arduino Binary Clock (hours, minutes and seconds)

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 $2 from EBay) 3-   2 S ...

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 ...
