In this project we will see how to build a smart bin. The system detects if the bin is already full and opens automatically when someone approaches.
What gives it an edge over other smart garbage cans on the market is that it uses a touch screen display that allows the user to interact and turn it on/off. The display is a 4D Systems gen4-uLCD-50DCT-CLB, it is a 5-inch capacitive touch module controlled by an Arduino Uno with the help of ViSi Environment in the Workshop4 pro version.
In addition we use two HC-SR04 ultrasonic sensors to detect when someone approaches and MG996R servos for opening and closing. Below is the general scheme.
Awesome and insightful design that would support contactless surfaces there by reducing the transmission of pathogens
