Learn how to build two different clocks. The first clock can adjust the time by using an hours and minutes button. You also learn how to create an animation.
The second clock makes it possible to adjust the hours, minutes and seconds by using a menu. You also learn how to use interrupts and debounce for your buttons.
We also going to replace delay() with millis(), and learn how to detect whether a button hasn't been pressed for a certain period of time.
I explain the mistakes I've made while creating this project, so you don't have to make them as well.
