Custom Keypress Intercepting Hardware

Project Description
Our customer required a small piece of hardware that could sit between the vending machine computer and the selection entry keypad. This device sent all button presses to the telemetry device. The telemetry device could then send the same button presses to the vending machine computer back through the interceptor device. This device could change the selection made by a customer. For example if the customer selected sprite we could intercept that selection and change it to pepsi. The main use for this device was to allow a customer to make a selection using a mobile device connected to the telemetry hardware via Bluetooth LE.
