- Delay – A pause in the program
- In Arduino: delay(1000) pauses for 1000 milliseconds (1 second) before moving to the next command.
- Simple but blocks all other actions during the pause.
- Timer – Tracks elapsed time without stopping the program
- In Arduino: millis() returns the time in milliseconds since the board was powered on.
- Allows multitasking (e.g., blinking an LED while reading a sensor).
- Sequence Control – Arranging multiple actions in the right order and at the right speed.
