Candy & Prize Dispenser–Educational Math Challenge

This is an educational math-based prize dispenser powered by an Arduino Uno, designed to reward kids (or curious minds) with a candy only if they solve a math challenge! The difficulty levels can be customized via keypad, and every expression is dynamically generated with increasing complexity.Ideal for STEM learning, classroom challenges, or as a fun escape room element for children.I’ve attached both the .ino sketch and the wiring instructions .txt file to this post.Note: To create the transparent prize window, mount a rectangular piece of plexiglass or an acetate sheet over the top of the dispenser box. This will let users see the candy or prize inside while keeping it securely enclosed. Enjoy building your Candy & Prize Dispenser!
