This is a classic security project that demonstrates the application of OR and NOT gates.
: A hardware-only circuit for a multi-story building that tracks and displays the elevator's current floor. Educational Instruments :
These projects typically fall into three levels of complexity: Foundational Verification : Simple circuits like a Light Detector using NAND Gates AND/OR gate truth table testers built on breadboards. Combinational Logic Systems : More advanced "decision-making" circuits such as Security Code Logic with Keypads Tablet-bottling counters E-voting systems Sequential Logic Applications : Projects utilizing memory elements like flip-flops for Digital Alarm Clocks Stopwatches Elevator controllers for multi-story buildings.
