Programmable digital code lock system is a high security code lock system that can be used to lock electronic devices such as Television set, computer system and other electrical appliances [5]. 555 Timer Based Simple Electronic Code Lock Circuit In this simple circuit we are building 555 Timer IC based Code Lock. In this Lock, there will be 8 buttons and one needs to press specific four buttons simultaneously to unlock the Lock. The 555 IC is configured as a Monostable Vibrator here. Simple bination Lock | Digital Integrated Circuits ... In this experiment, I do not describe how to work this circuit into a real security system or lock mechanism, but only how to make it recognize a pre entered code. The “key” code that must be matched at the data entry switch array should be hidden from view, of course. Digital Door Lock Password Security Code Lock using 8051 This Digital Door Lock – is simply a password based electronic code lock designed using 8051 micro controller, a keypad and a 12 volt dc relay. In this article, we have designed a simple digital door lock using 8051 which can be used as a security checking system to limit access to an area room only for certain individuals with the password. door lock circuit : Security Circuits :: Next.gr A programmable code lock can be used for numerous applications in which access to an article gadget is to be restricted to a limited number of persons.

Usually ships within 6 to 10 days. Homello RFID Electronic Cabinet Lock Hidden DIY for Wooden Drawer Cabinet Locker, Easy to Use & Programmable. 4.0 out of 5 stars 46. NEED thermostat with LOCK feature The LPA I need a thermostat that can never be changed by a tenant. I bought one at Menards and they figured out how to override the lock out feature. Neither Menardsn or Home Depot sell thermostats that require a four digit code to make adjustments. Password Based Door Lock System using 8051 Microcontroller Once the code is compiled, a hex file is created. In the next step, we use Proteus software to draw the circuit. The code is dumped into the microcontroller using an external programmer and Willar Software. Recommend Reading: Password Based Circuit Breaker Project Circuit Diagram and Working.
