Vending Machine with RFID

A simple code and design to build a vending machine with cardboard or a 3D printer!

I’ve seen so many YouTube videos and pictures of people making things like this however they never gave the code; so, I decided to make my own, the code for this was made especially for a vending machine or other things similar.

How does it work:
To make this work you need to replace the RFID chip UID in the code with your own, after only the specified chip will be able to work. after you can set a 4-digit pin number with no letters to have as extra security.

On the breadboard, you can have a yellow LED or buzzer however buzzer is quite obnoxious.”
