An arduino based clock with 1ms accuracy over a year. Time stored in RTC continually updated by GPS module - lcsaszar/Super-Accurate-Arduino-Clock-V.KEL ...

While the build in GPS works well, it can be an issue within well insulated home to receive GPS/ DCF signals from the outside. Hence the wish to add NTP with the needed hardware and code to get a ...

Simple clock that always shows the correct time. GPS reception is required. Selection between summer and winter time must be done manually. Only a few components and easy to build even on a breadboard ...

It’s a relatively simple hardware build in that it is simply an Arduino Nano, GPS module, and e-ink display module wired together, but it provides an interesting exercise in running through the ...

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.
