This is a simple school project for programming with AVR MCU (Curiosity nano) in MPLAB X IDE. The project simulates a vending machine that accepts coins and dispenses products based on user selection.
I also used this project as an opportunity to learn how to design an enclosure and use a laser cutter to build it.
