Smart Trash Bin is a Trash Bin that can open if you want to throw your trash. The Smart Trash Bin contains some components like UltraSonic Sensor, Servo, Jumper Wire, Microbit, and IOBit. How it works is, the UltraSonic Sensor of the Smart Trash Bin detects your hands when your hands are near the trash, and when its detected, the Servo of the Smart Trash Bin will move and open the Trash Bin so that you can throw your trash.
