What you'll build
Design your own light shows with multiple LEDs and code loops.
Before you start
You'll learn: Using an array of pin numbers plus a for loop to drive many LEDs with a few lines of code.
You'll finish: Five LEDs playing chase-forward, chase-back and group-flash patterns.
Real world: Billboards, stage lighting and scoreboard displays are just bigger versions of this array-and-loop idea.
Then try: Invent a pattern that spells your initials in flashes, or a warning pattern for a level crossing.
Who does this: Lighting or display technician — TVET, or software development at a coding school like WeThinkCode.
