Global IoT Dashboards: SmarTrash Cloud Games

An automated trash can that just opens its lid is extremely basic. The SmarTrash Cloud Games project transforms a boring household appliance into a global, gamified, internet-connected arcade machine. By combining the massive IoT capabilities of the ESP8266 Wi-Fi architecture with HC-SR04 sonar detection, the bin calculates exactly how many times it was used and violently blasts those statistics up into the Arduino Cloud!

Over-The-Air Variables (Arduino IoT Cloud)

This project requires fully abandoning standard 16x2 LCD screens and ascending to the Azure/AWS backed Arduino IoT Cloud.

1. In the Web Dashboard matrix, the programmer creates an integer variable: trashesThrown.
2. This variable is marked as READ/WRITE and completely syncs to the physical silicon chip via secure thingProperties.h WebSockets!
3. The Sensor Event Trap: The physical HC-SR04 ultrasonic array pings locally.

if (distance < 15 && lidIsClosed == true) {
  openServoLid();
  trashesThrown++; // Increment the global counter variable!
  // The moment the variable changes locally, the Cloud library silently 
  // establishes a massive TCP/IP packet transmission and fires it to the global server!
}

The Webhook API Leaderboard Structure

Because the trashesThrown variable is pushed to the global server, you can attach an API "Webhook" inside the Arduino Cloud.

• Every time the variable increments, the Cloud automatically fires an HTTP POST payload over into a massive Google Sheets Script or an external Discord Bot API Server!
• The Discord bot intercepts the JSON string {"trashesThrown": 42} and instantly posts in a public chat server: @User1 just leveled up their Sanitation Score to Rank 4!
• The physical user gets visual feedback when the bin flashes massive Neopixels (Green for points, Rainbow for a level up!).

The Hyper-Connected Sanitation Kit

• NodeMCU ESP8266, ESP32, or Arduino Nano 33 IoT (Native Wi-Fi chip integration is mandatory. Bluetooth cannot reach Azure servers!).
• HC-SR04 Ultrasonic Sonar Component.
• Heavy Duty MG996R Metal Servos (To throw open the massive bucket lid thousands of times without failing).
• An active Arduino IoT Cloud Account.
