Hi,

Here are some screenshots of the realization of a personal project of a FPV car that should be drivable on a PC as a video game. There car is driven by an Arduino Nano 33 IOT that is exchanging data between the car and the computer in real time thanks to a WiFi-connection. 
An important required component was an increment-counter in order to measure speed. An optical sensor is counting the "tops" that are given by the rotation of a toothed wheel with correct dimensions that was missing.

Thanks to 3DEXPERIENCE Lab for having helped me to produce this part !
