Often you might see a recycling bin next to a trash can, and notice that someone else has thrown their waste into the wrong container. To help with this conundrum, the team of Shalin Jain, Viraj Singh, Edward Chen, and Joshua Kim created a double-sided container that sorts things automatically.

Their device, dubbed “Splash,” takes a webcam image of the item presented to it, analyzes this with a Python script and the Azure Custom Vision API, and reports back to an Arduino Uno controller with its findings. Depending on the results, the Arduino then uses a driver board and motor to properly position a flap, directing refuse into in the correct bin.
