First post here so sorry if its wrong but what if you could make a project where you press buttons and food comes out a vending machine that would be cool

Bump

I suppose that could work if you coded it on Scratch on a Raspberry Pi… (The version of Scratch on Pi has extensions that let you control the GPIO pins)

This initially sounds crazy but is possible. With Lego EV3 (discontinued, but eBay has it) you could use the motors to open/close a hatch, spin stuff, etc. Additionally, the Scratch on a Raspberry Pi could work. It would be hard but not impossible.
