Que fait ce projet ?
Tri des déchets sur un convoyeur :
- À partir d'un bouton poussoir
- En théorie à distance à partir d'une application
Liste des composants
- 2 moteurs
- 1 bouton poussoir
- Structure en bois
- Fils électriques
- Wemos D1 mini (sorte de mini-carte Arduino)
- Sac poubelle pour le convoyeur
Fabrication du convoyeur

/*
This sketch demonstrates how to set up a simple HTTP-like server.
The server will set a GPIO pin depending on the request
http://server_ip/gpio/0 will set the GPIO2 low,
http://server_ip/gpio/1 will set the GPIO2 high
server_ip is the IP address of the ESP8266 module, will be
printed to Serial when the module is connected.
