Project Description
The smart dustbin uses an Ultrasonic sensor HC-SR04 to detect objects in front. It then sends the signals to Arduino Uno. The Arduino understands the signal and sends a signal to the Servo Motor which opens the flap on top of the dustbin. Here we have programmed it to open the race for only 3 seconds after 3 seconds the flap automatically closes. You can change that time just by making minor changes to the code in Arduino IDE.
