Chess clock build

1

Hi everybody, i am about to start a project for a chess clock. I will use a pico (none wireless), do you think i should use a RTC for the timing or simply the internàl counter in the pico. I will be using micropython.

Thanks.

Usually a chess clock will only tick down the time between moves. For this purpose the internal counter is perfectly adequate. If you wanted to add more features to your clock, such as recording the start and end time of a match, or advising the players of when to break for refreshments, then a RTC module would be useful.

Thanks Jeff, thats what i thought as well, i may also use it for a board game timer but even then a RTC would not be required. Cheers.
