Clocks are a popular project on Hackaday. They’re a great way to showcase a whole range of creative build techniques, and can make an excellent showpiece as well. We’ve seen everything from the blinkiest binary build to the noisiest alarms, but [Benoit] has delivered something different — a stylish build that looks like it came right off the store shelf. The clock features a large 7-segment display built wi ...

In this project, we will learn the basics of User Datagram Protocol (UDP). We will request and receive time from the NTP server using the above communication protocol. The 4Duino display is utilised to print the received time in both, digital and analogue clock format. Transfer of Data over Internet The 2 most common ways to transfer chunks of data (also known as packets) over the internet are Transmission ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is reconnected, it displays the real time irespective to the time and duration it was in off state. In this project we have used a 16x2 LCD module to display the time in - (hour, minute, seconds, date, month and year) ...

Hardware components: Atmel ATTiny85 × 1 SparkFun Tiny AVR Programmer × 1 Software apps and online services: Arduino IDE   STORY Introduction The Atmel tinyAVR MCU's (ATtiny) are a series of chips optimized for applications requiring performance and/or power efficiency in a small package. These have internal clocks that runs at 8 MHz. They can also be clocked at 16 MHz and 20MHz using an external clock. ...

This is a clock designed to keep accurate time (independent of atomic or GPS), display local sunrise, sunset and solar noon, and also adjust itself for daylight savings time. I wanted the clock to be easy to use and be flexible. The setting functions are menu-driven, you set each parameter one digit at a time (with live data validation) and you can abandon changes if you want. You can have 12 or 24-hour tim ...

This is a very odd kind of clock, which can easily be made with simple supplies. To begin the explanation, I would like to say that I have always wanted time to be metric. 5 o'clock would be mid-day, 7:5 would be three quarters (6:00 pm), and so on. This prototype tells deci-days, centi-days, and milli-days, in that order. For those that are unfamiliar, ten deci-days are in a day, ten centi-days are in a de ...

Introduction In this project, 16 LEDs are used to represent the time in binary. The time is read from a Real Time Clock breakout board - the same one used in the Digital Clock page. The binary clock uses 4 place values for the hour (12hr format), 6 place values for the minutes, and 6 for the seconds. So the following pattern...   ... makes the time, 8+2 = 10 hours, 16 + 4 + 1 = 21 minutes, 4+2+1 = 7 se ...

Updated Aug 4, 2011 A streamlined version is now described here. Beside the enclosure, the original feature of IllyClock is showing the time in colors: 3 hours before wake-up time, color changes from green to orange; 1 hour before wake-up, the time is shown in red. One can estimate how much sleep is left just by squinting at the clock. Parts you will need: - Illy coffee can (250g); chosen because it is easy ...

nspired by drj113's great instructable on making a word clock, I wanted to make my own.  After seeing the (extremely overpriced) commercial "qlocktwo" word clock, I decided to borrow its smooth glossy black design while basing the innards of my clock on drj113's design. In the end, I managed to stuff the arduino and LED's inside an IKEA shadow box, and used printed transparencies to create the black letter ...

Have you ever wished lunchtime were longer, but didn't know where to find those few extra minutes? Well, wish no longer! Thanks to great in advances in clock technology, I present to you a clock that speeds up 20% every day at 11:00 and slows down 20% every day at 11:48, giving you an extra twelve minutes of lunch to enjoy. Twelve minutes may not seem like a lot but, to put it into perspective, this is a fu ...

I had a Holux M-1000B Bluetooth GPS module that was just gathering dust in my room. I had bought it from DealExtreme back in the days when I had GPS-less (but external GPS capable) Nokia E51. Upgrading to a Nokia E52 has since made this receiver redundant. However, since getting an Arduino, and being put off by the price of GPS shields for them, I decided to use the GPS receiver I already have. Once the rec ...

I wanted to learn how to interface with I²C devices using my Arduino, so I bought a DS1307 clock and crystal kit from Earthshine Electronics. I've no association to them, but I'd recommend having a look at their shop. Their prices are very reasonable, unlike most Arduino component retailers. I²C is an addressable serial interface. That means that you can communicate with many I²C devices using the same 4 pi ...
