Quick question about th eelectronic lock using the 8051 chip…
Can I program it to light a LED or ring a buzzer if the wrong code is entered 3 times? I can see applying a relay that will be activated upon the lock code and deactivated for the unlock code, but I’d also like a buzzer to go off or an LED light if the wrong code is entered 3 times instead of it simply stating that “wrong code entered” on the LCD screen.
thank you!
