Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult with… ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino… ...

Using Arduino Nano 33 IoT or Particle Photon you can connect the clock via wifi to the NTP time server or cloud to synchronize time.

Some of our readers will remember the Qlocktwo clock, that display the time in words rather than numbers, now you can make your own DIY version using the power of Arduino.

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino-based DOTKLOK. Basically, you can get a bunch of different ways to tell time. Different ...

My phones ignore the NTP server from the DHCP server and go off and get the time themselves from elsewhere. Not sure if it's GSM or NTP but it's out from my domain controller which I have to ...
