Description: Electronic locks on the three passwords, the input, the control section and output components. Enter some of which include 4 × 4 matrix keyboard, bounce elimination circuit, the keyboard scanning circuit, the keyboard decoder circuit control section includes key memory circuits, the password modify the circuit to compare the circuit output part of the main seven-segment display decoder. When you enter the correct password three, a L1 LED light to indicate the door open When you enter your password wrong, the other a light-emitting diode light, then you can unlock switch (reset switch) to re-enter the password. To achieve the password changes, press the lock switch can be re-set the password, that password change functionality to achieve.
