I recently received a grant to set up a vending machine in town to freely distribute outreach supplies to community members 24/7. I have acquired the vending machine (no make or model number, the manual is unhelpful), but getting it to go into free mode is proving difficult. The machine and motors work fine if I were collecting money, but get glitchy trying to get it into the gift goods mode.
I was wondering if anyone might be able to help me scrap the complicated piece of it and turn down the business logic to something much more simple - someone I know mentioned Raspberry pi. Ideally it would look more like 1. User presses a button 2. Something displays on the screen to confirm user input 3. the springs twist releasing the supplies.
:Let me know what you think - If anyone is able to help me with this, I think this would make the machine a lot simpler and easier to troubleshoot in the future, hopefully making this project last a long time.
