This was a fun project I built using a perf-board Arduino with GPS receiver, some LEDs, some long wire, some clever code, and a car! <\/p>\n

I have this friend<\/em> that has a speeding problem. So I built this device for my friend<\/em> so he’ll know when he’s speeding. How will he know? Because when the small perf-board Arduino device with a GPS module detects that his vehicle’s speed is over the speed limit, it turns on a police lights display that is mounted on the inside of his car’s rear windshield. When he sees those flashing police lights in the rear-view mirror, he’ll know he needs to slow down!<\/p>\n
