salut pour ceux qui connaisse connecter un sonar comme celui la faut il l'activer a part du allhold ? ou ?
Google "APM HC-SR04" donne quelques pistes pertinentes:
We don’t support that sonar, it has pretty bad performance.
Tu as donc tous les conseils avisés pour la suite à donner,As I have posted on a few different threads on a few different forums the SR04 is less than worthless. It only "kind" of works when it is pointed directly at a VERY smooth surface and after a foot or so even then the return signal is so sporadic that it is just worthless. The scatter is horrible, the resolution is horrible.
Do yourself a favor and toss them in your "no good" parts drawer and be done with it. I have probably 10 or so in my bin drawer.
