Current State of Affairs
Brad has built some custom boards with PCA9554N I/O Port chips on them. There is an input board, with 22 screw terminals to be connected to any buttons on the device, an output board, with 22 relays to trigger the 22 motors to vend products, and a rPi to handle i2c protocol between the PCA9554N chips. -Jared
As of August 25, 2015, the I/O boards and RPI can successfully trigger each motor individually, and code has been written in python on functions such as tablature, stocking, and interpreting I/O boards. (Thanks Hunter!)
Gary has built a first-run prototype of a transparent coin acceptor that will pass coins in front of the glass display on the front of the vending machine.
Jared signed up for a square account to get a card reader and is donating an iphone4 to be used in conjunction to accept cards for products on Dec 14, 2015.
Jared got a square card reader, it is connected to the iphone 4.
The Adafruit display is mounted inside the vending machine.

- Hook up screen to RPI.
- Modify Gary's coin acceptor design to work in the machine.
- Collect stock of the kinds of supplies that LVL1 wants stocked in the device.
- Interface the iPhone4 with the square card reader with the rPi.
