Créer un bouton sans fil sous esp8266 (01/01s) pour démarrer son PC (magic packet)
#main.py Projet à télécharger ici https://monkeytime.be/blog/data/medias/powa.zip
Je l'ai créer avec ce type de bouton acheté sur Amazon en lui adaptant un petit boitier pour contenir l'électronique et ce petit bouton power.
