In this project we will learn how to make an Arduino based DIY vending machine. I will show you the entire process of build it, starting from cutting and assembling the MDF boards, to connecting all electronic parts together and writing the Arduino code.

The vending machine features four discharging units controlled via four continuous rotation servo motors, a carrier system controlled via stepper motors, an LCD, four buttons for selecting an item and a coin detector.

You might be thinking now that the item carrier is not so useful for this vending machine, and yes, you are probably right. But my idea here was to make this project more interesting or a bit more complex so you can learn more new stuff. I think this project idea can be great for electronics or mechatronics students considering building one as their final year project, as well as for any Arduino enthusiasts.”
