This circuit uses a relay for controlling any type of device CD4017 code lock with wrong code detection February 28, 2021 • project Some time ago we learned how to use the CD4017 decimal counter The post explains a simple failproof digital keypad security lock circuit using a keypad module and a single CMOS IC . This circuit may be applied to activate a relay for This is a video tutorial designed to walk hobby electronics enthusiasts through building a working keypad combination lock circuit using various electronics components. This circuit may be applied to activate a relay for controlling (on & off) I've always wondered how did electronic locks work, so once i finished the basic digital electronics course I decided to build one myself. This This is a video tutorial designed to walk hobby electronics enthusiasts through building a working keypad combination lock circuit using various electronics components. And I´ll help you to build This simple combination lock accommodates codes from 1-9 digits long, with the only restriction being that the same digit cannot be used twice. In this tutorial, we are going to make a simple transistor code lock circuit. To open a the lock which is connected to the K1 Load you must press each momentary switch in the correct sequence. In the design I have explained in this article, however, no complex electronic circuits or ICs or keypads are used, rather the system uses a few In this experiment, you will likely locate the two switch assemblies on two different breadboards, but it is entirely possible to build the circuit using just a single (8-position) DIP switch assembly. The circuit shows strapping for a 4-digit code, in this case This circuit is very basic to build. This is the circuit diagram of a simple electronic combination lock using IC LS 7220.
