I am a high school student,16, and I adore what we can make with Arduino !
I ve decided to create a smart parking( a miniature): sensors (not capteur sorry ), motor(which type), 7 segment display to count available places and an arduino uno to get it all working
But I don't have a clear way to do it... only stuck in my ideas...
Are you making something for toy cars or real ones? The hackaday link you posted explains how the sensor is made that they detect the toy cars with. For real cars it will be more difficult to safely and securely detect cars.
