BOM for Math Candy Dispenser Materials I'll Need: 4x4 Matrix Keypad – Used for input of equation solutions. Servo – For candy dispensing mechanism. LCD Module – Displays math equations and feedback messages. LEGO/Cardboard – Forms the base and structure of the entire enclosure. Candiy  – Small candies to be dispensed by the system. Arduino UNO  - Microcontroller for controlling the whole system. Programming Cable for Arduino Uno – Connects the Arduino to a computer for uploading code. Knowledge I'll Need: How to create a function that will generate random equations and their solution. Coding the user inputs, validating answers, and controlling the outputs. How to properly connect the LCD screen and keypad to communicate with the microcontroller. Creating a proper stable dispensing mechanism using the servo motor that will dispense the right amount of candy.

Final Project Summary Project Title : Password-protected Candy dispenser Objective : Math based lock system where users must solve a randomly generated math equation displayed on an LCD to earn a candy. How It Works : The Arduino generates a simple math problem and displays it on the LCD. Users input their answer using a keypad. If the answer is correct, the system dispenses candy using a motorized mechanism and displays a success message. Incorrect answers prompt feedback on the LCD screen, and lets the user try again. Challenges : How to create the dispensing mechanism (servo motor)
