14-year-old Australian maker Lochie Ferrier bought an Airwick automatic air freshener and after its overpriced scent cartridge died, it sat around until Lochie realized it has a big ole PIR on the front. He hooked up an Arduino and proto shield and set it to play the Mario theme when the PIR detects movement.
