Overview
Working in a team of five, I designed and programmed a trash can that opens itself.
How it works
- I built a circuit on a Raspberry Pi with a sensor that detects sound.
- I wrote C++ for the Raspberry Pi to switch on a light source on the board when it hears the cue.
- A LEGO EV3 reads that light with its own sensor, then opens the lid with an arm motor.
