by Lucky @ elektormagazine.com build a LED display clock able to display temperature, humidity and air pressure. He writes: What do you do when you want to design ‘something’ with a vintage or modern display? A clock of course, and this is our first design with RGBDigits:...

Using Adafruit's 0.56" 7-segment LED backpack and display and the DS1307 RTC (Real Time Clock) board, this tutorial will guide you to make a simple 4-digit clock that uses only 2 Arduino pins. The 7-Segment Backpack is a combination of the LED display, header pins, and a PCB which need...

David Johnson-Davies designed a minimalist ATtiny85-based watch using 12 LEDs, arranged like a clock face, to show the time in analogue-style. He writes: To show the time you press the button on the watch face, and the time is then displayed for four seconds. It lights one LED to...

Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231...

Sverre Holm blogged about his Arduino clock project: But I needed another Arduino project as I had made a K3NG morse keyer. I love this keyer because it is unique in supporting a display where you can see what you send. But I wasn't using the morse keyer all the time, so I wanted...

Scott from SWHarden has published a new build: Today I made a high frequency multiplier using a single component: the ICS501 PLL clock multiplier IC. This chip provides 2x, 5x, 8x (and more) clock multiplication using an internal phased-lock loop (PLL). At less than a dollar on eBay,...

Thanks to Internet, the problem of time shifting in embedded and connected devices was solved using time synchronization over Internet. National Institute of Standards and Technology provides a service called Network Time Service (NTS) over the Internet. The project of ESP8266-based...

andrea biffi @ instructables.com has a detailed tutorial on how to build your own Nixie clock using IN-4 tubes and Atmel ATMega168 microcontroller. Nixies are neon valve tubes, where ten cathodes have shape of digits and are lighted up by plasma when high voltage flows through them....
