Tick the clock
The clock hand turns smoothly. Make it tick: it should jump 30° once every second, one full turn every 12 seconds, starting at 0°.
Only the timing function should change.
What Check tests
- At 0.9 s the hand is still at 0°
- At 1.1 s it has jumped to 30°
- It never shows a value between two ticks
Stuck? One hint at a time
The solution unlocks after your first Check. Try first: that is where the learning happens.
