PCB and software for an led clock.
License: MIT License
This is the pcb and software for a clock showing the time as three vertical led bars.
The hours are split in two bars, 13h to 23h and 1h-12h, while minutes are split in three groups of 15, 5 and single minutes. Summed up you can read the time.
Time is kept with an RTC-DS3231. Because the outputs of the arduino uno are not sufficient, shift registers are used to output the time.
Result:
Please contact me via github if you have any questions or want to rebuild this clock 😉.
