Everything is getting smarter these days? So why not your trash can?
This trash can opens and closes its lid if it sees any trash in front of it. You just need to bring the trash to it and it will open automatically and will wait for you to feed it. Then after a certain delay it will close automatically. Watch the video to see exactly what it can do.
This is the source code of the Arduino uno program (.ino sketch file) that is running on the DIY Arduino kit ultrasonic automatic trash can.
