PRACTICAL APPLICATIONS
Blinking Multiple LEDs at different speeds.
Simple Light Show: Turn on and off LEDs in a pattern.
Traffic Light Logic: Red, yellow, green in a timed cycle.
REVISIT
▶ Outputs toggle devices (like LEDs) ON or OFF.
▶ Wait blocks insert time delays, orchestrating sequences.
▶ Pin assignments must match the physical wiring.
▶ Projects such as a traffic light show how we integrate multiple outputs with carefully planned timing.
