Digital (Electronic) Locker

Electronic Locker is a system that is used to secure your valuable things. In this paper, an electronic lock that lock or unlock by correct sequence of four-digit key or password. These key or password can be changed at any time. Also, if a wrong key sequence is entered, then it will produce an alarm signal. Along with these if user take more than 10 seconds to press two subsequent correct keys, then it will produce a timed- out signal. The complete design of Electronic Locker is developed using Finite State Machine (FSM) and has been written in Verilog HDL (Hardware Description Language). Also, the complete design is simulated and synthesized in Xilinx ISE design suit. The complete design is also implemented on Artrix7 DDR4 FPGA hardware board.
