Electronic Safe Project

Students will use concepts and skills they developed in previous labs to design and build an electronic safe with a 4-digit password. This lab will reinforce the practical application of combinational logic circuits and revisit how flip flops are used to create shift registers. Students can optionally complete advanced challenges like adding a solenoid to physically simulate opening a safe door.
