VendGame is a free drop digital vending machine developed by me from scratch (Software/Hardware everything in 1-2 months). It's my own product for in-store sampling and branded giveaways. I developed it's whole architecture very flexible that (on front end) the app can be developed on any technology like Unity, HTML5, Flash and any technology you can think of and that app/game can be easily connected to this VendGame without a single change.
I wrote a bridge on Python that helps in communication between high and low level code. Arduino is used to control it's machinery ie: Servos, Lasers, Lights and DC Motors. And in the last obviously I individually developed this app without a team
