fonctionne comme annoncé
I'm using a couple of these two control some switches on different household applications. On the plus side, they were very easy to set up and use. On the minus, they do seem to wear out after a while.
works as advertised
J'utilise quelques-uns de ces deux boutons de contrôle pour des applications domestiques différentes. Sur le plan positif, ils étaient très faciles à configurer et à utiliser. Sur le plan négatif, ils semblent s'user au bout d'un moment.
Pro: J'aime le faible encombrement de ce module de relais et vous pouvez le connecter à toutes les broches Arduino que vous souhaitez utiliser, ce qui vous permet d'éviter tout conflit de broches avec certains mélanges de relais à blindage. Con: Les trous de montage sur le côté avec les bornes à vis sont trop proches du bornier à vis pour obtenir un écrou ou une vis sur un support de montage, si vous voulez le monter.
