Started as a simple concept by interfacing android mobile device to raspberry pi 3. The idea kicks off, but after a few weeks I ended up in different revisions of the Android SDK,Nodejs and python script.
A lesson learned from the experience that when the project kicks-off, should not start coding right away, if you will do that then the result was more often codebase will become a tangled mess.
An important step was to create a prototype that wraps the solutions into a rudimentary machine. Tada!! It works, the machine was successfully working with hard-work and self-determination.
On midway 2018, I brought the machine outside fabrication for actual testing. Yes got a bunch of people onboard for testing and it was a success, the only thing that I needed to consider was to enhance the security of the machine.
Including in the developments are some modifications of the Android Tablet OS. The splash screen has been modified and the android app autostarts like kiosk mode.
This project was a big success but I am still thinking out of the box the next step and future of my simple vending machine.
