Deck out your ride with an Arduino-controlled spoiler
Car spoilers can provide downforce for better performance, or simply give the appearance of speed. To take things to another level, Michael Rechtin designed his own custom wing that doesn’t just sit there, but pitches up and down via a pair of servos.
The system utilizes an Arduino Nano along with an MPU-6050 for control, adjusting itself based on his Mazda’s movement, and powered is supplied by a LiPo battery. Suction cups are used to attach the spoiler, so installation appears to require no actual modification of the car whatsoever.
As far as performance goes, Rechtin notes that it’s just for fun — likely wreaking havoc on your gas mileage!
