The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

This clock uses a DS3231 RTC IC, which is not only quite accurate, but does also provide a temperature reading (which isn't as accurate but good enough). In order to switch between the normal ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano. The small Arduino ...
