Open Trash Can

* indicates required

This project started out serious, then I kept thinking of funny things I wanted to make it do, so this turned out to be a pretty complicated trash can. The only way I could think to present it was a corny infomercial style video. It talks, sends you an email when its full, and I made an accompanying Android App for more control over its functionality.

You need:

A cheap trash can (this one is from Target)

Computer Speakers

An Arduino Leonardo

An Iduino Yun Shield

An Elechouse MP3 Shield

Googly Eyes (don't skimp on these, get the good ones)

A 4GB SD Card

A Micro Servo Motor

2 HC-Sr04 Range Sensors

Some Jumper Wires

A Hot Glue Gun

A Mini Breadboard

An Bluetooth Module

A 9V battery or Wall Adapter (to power the Arduino board)

Hey !!!

about us (me).

My name is Matthew and I attend the University of Pittsurgh. Currently I am a junior, going for a bachelors in Information Science. I am always looking for someone that would like to embark on a new project or startup. I work as a food server when I am not at school, but would love something a little more technical, if anyone is hiring.
