Smart Dustbin: IoT with Arduino, Python, Kotlin & Azure
A university project where I built a garbage bin that knows how full it is and tells you about it. An ultrasonic sensor measures the fill level, an ESP8266 sends the data over WiFi, and you can monitor it from a desktop GUI or an Android app. The Hardware An Arduino Uno with an HC-SR04 ultrasonic sensor measures distance to the garbage surface. A servo motor opens the lid when someone approaches (second ultrasonic sensor detects proximity). The Arduino sends distance readings over serial to an ESP8266, which transmits them over WiFi. ...
