Auto-Bin
By : Haris Panca
Muhammad EfantamaKenanga Ayu Nirmala
This idea we got when we pay attention to our surroundings clean, some people less lazy throw away trash in its place amongst other things because, if we have to throw away trash pressing or touching the dumpster, therefore we have an idea to make project of the instrumentation, entitled "Trash" that can open and close automatically so that people will dump need not be touching or tapping the dumpster.
To bring back the community will want to dispose of the waste in place, some of the trash made as attractive as possible so that the public are interested to dump garbage at the venue. One of them, namely the trash with an automated system where to open the dumpster, users do not need to touch the dumpster. Users only need to stand in front of the Ultrasonic sensors on the front, then the bin will open automatically. In addition the bin is equipped with LEDs so that when the bin is open green light will turn on and when the trash can close the light is red.
