Our Maker lab class created a device using the cloud bit. Attached to one group of bits was the cloud bit and a motion sensor which was placed inside the machine to trigger an MP3 player when a drink was retrieved.
The mp3 player was loaded with compliments and pep from a computer voice and from phrases recorded by the students.
On top of the other vending machine was a cloud bit receiving and triggering the mp3 player attached to a speaker.
We found that the cloud bit had troubles when placed in the location we were with spotty WIFI, so ultimately the class decided to trigger the the mp3 player with a pressure sensor.
In the second version, the pressure sensor was placed over the coke button and triggered an odd compliment.
