In this article, we will be discussing how to make an electronic keyless door locks system. We will start by explaining what you need to do for the project, then move on to the circuit diagram and code. Finally, we will show you how to assemble and test the system.
What You Need
You will need some basic hardware and electronics skills for this one.
The first step is to gather all of your materials. You’ll need a piece of wood, a drill, a saw, a doorknob, screws, sandpaper, paint, and varnish for the lock itself. You’ll also need an electronic keypad, an electromagnet, and a battery pack. If you want to get really fancy, you can add an LED light that will turn on when the lock is activated.
The second step is to drill a hole in the piece of wood that is big enough for the doorknob to fit through. Once the hole is drilled, see out a slot that is big enough for the keypad to fit into. Sand down all of the rough edges and then paint or varnish the wood.
The third step is to assemble the keypad. This involves soldering wires to the appropriate terminals on the keypad and then attaching them to the piece of wood with screws.
The fourth step is to connect the electromagnet to the battery pack. Once everything is connected, you can test your new door lock by pressing the keys on the keypad. You can screw on the door knob and enjoy your new electronic door lock if everything works!
The Circuit Diagram
A circuit diagram is a simple way to represent how an electronic door lock system works. It consists of a power source, a switch, and an LED. The power source provides the electricity needed to operate the system. The switch controls the flow of electricity to the LED. When the switch is turned on, electricity flows to the LED and lights it up. When the switch is turned off, electricity does not flow to the LED and remains dark. The circuit diagram shows how these three components are connected together to create an electronic door lock system.
The Code
The code for this project is very simple. All you need to do is connect the power source to the switch and the LED. Then, when you press the keys on the keypad, the switch will turn on, and electricity will flow to the LED, lighting it up.
Assembling The System
Now that you have the components, it’s time to put everything together. Start by screwing the door knob into the hole you drilled in the piece of wood. Then, attach the keypad to the wood with screws. Next, connect the electromagnet to the battery pack. Finally, screw on the door knob and test your new electronic door lock!
Testing The System
To test your new door lock, simply press the keys on the keypad. If everything is working properly, the LED should light up. Now screw on the door knob and use your new electronic door lock!
