This project develops an interactive puzzle box with an electronic locking mechanism to engage young learners in logical problem-solving. The box features a series of switches and LEDs, and the user must find the correct combination of flipped switches to activate all the LEDs and unlock the box. A custom logic circuit, using AND and NOT gates, encourages iterative problem-solving. Concealed within the box, this innovative circuit adds an unexpected level of challenge that is more than one may initially expect. The box is designed to provide a hands-on learning experience, employing a reward system designed to foster persistence and critical thinking. The project also explores the educational potential of the puzzle box as a tool for teaching foundational engineering logic to young children.
