Grumpy_Mike:
Given that

int maximumDistance = 50;  // distance Maximale acceptée (de 0-450 cm)

int minimumDistance = 0;  // distance Minimale acceptée (en cm)




The code

if (cm > distanceObstacle || cm  <= minimumDistance) {



Will always be true. Would you mean to AND those two statements and not OR them?

That is && in place of ||

cm <= minimumDistance is false unless cm = 0. So it's pretty much redundant in this situation.

The thing evaluates to true the moment cm > distanceObstacle is true, which would be cm > 10. That's sensible. Then the PasObstacle is set true, and the normal movement is done. To me this part actually looks correct.
