*Clock with timer* You can keep track of what time it is or set the timer for minutes (1 - 90) and seconds (1 - 59). Setting timer Use the button "set the timer". Use buttons "set seconds" or "set minutes" to set the desired time. You can reset minutes and seconds by pressing "reset" button. Touch save. If you want to stop countdown press "stop" button. Maybe it doesn't show absolutely accurate time.
All code by me. Sounds and effects are from scratch library.
