Note d'intention
Une camera de video surveillance declenchant son et lumiere au passage des passants. La camera filme l'instant festif.
Références et liens
- Tutoriel ESP8266 :
Notes techniques et matériaux
- ESP32 cam Chez amazon
la camera envoie un flux video en wifi…eventuellement avec Motioneye (sur linux) on peut ajouter des fonction de detection mouvement/face etc… mais c'est sur linux et complexe.
- ESP8266 : Permet de commander en wifi l'allumage de LED et d'un module mp3 via une page web.
- Lecteur Redmp3 Amazon (se declenche avec une arduino ou esp..) necessite une carte micro SD et necessite un ampli et enceinte pour faire un son assez puissant…. ou enceinte bluetooth…batterie integrée. Fonctionne avec librairie Redmp3.h
- Jumper
- Breadboard
- Powerbank et peut être booster…
- Enceinte Bluetooth si besoin son fort
Esp8266 page web controle
Voir part 1 : https://randomnerdtutorials.com/esp8266-web-server/
- Dans arduino IDE ajouter http://arduino.esp8266.com/stable/package_esp8266com_index.json dans fichiers /preferences
- Ensuite dans outils/Gerer les bibliotheque ajouter ESP8266
- choisir Outils/type de carte : LOLIN(WEMOS) D1 D2 Mini
- Et utiliser le code fourni sur la page en mettant votre ssid et mdp de votre wifi…
Attention les GPIO du WEMOS D1 sont pas les meme que les numero de pins : voir Pinout diagram ici : https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/
Code
Pour l'instant juste un code qui crée une page internet avec 2 boutons controlant les GPIO4 et 5.
