==In-Depth: Smart Containers==


===Need===
Question: Is there enough flour and sugar at home to make a cake for your friend's birthday tomorrow? Or do you need to stop at the store on your way home?
===Concept===
Design containers for pantry bulk items that relay content levels to smart phone app in real time.
===Equipment===
* [[Arduino]]
* Sharp GP2D120XJ00F Analog Distance Sensor 4-30cm
* Container
* Computer
===Prototype===
(coming soon)
===Code===
