Home Security - Implement Code Lock to a Home Door



The previous circuit (Digital Code Lock) can be easily applied to a home door or a window by using a solenoid.

For that you require 12 volts / 2 pin solenoid. Simply connect the two terminals of the solenoid to the A and B terminals of the circuit.

If you really interested, you can implement so many useful applications by using this circuit.

Extra Protection to your car

Implementing Digital Code Lock to Vehicles (Fig. 010A)




This is a very important circuit for your vehicle. You can couple this circuit to the starter switch (Fig. 010B). Then the 4 - digit secrete code will be needed to start the vehicle. The code can be decided by you. You can change the code at any time with zero cost. Once you enter the code correctly only the starter path completes. (Ignition on)


Key Pad (Fig. 010C)

9- digit key pads are mostly available in the market and very cheap in price. No worries, if anyone cannot find it, you can make one on your own. You just need 9 touch switches and a small Vero board.

Mount the Keypad in your car’s dash board nicely. Add an extra value to your vehicle by installing this unit. Connect A abd B terminals of Fig. 010A and Fig. 010B. Set the 12V supply to the circuit by the car battery.


You will get an extra protection to your can and no one can steal without knowing your 4 – digit security code.

If you have any doubt, please fell free to contact me via ciscocelincomf@gmail.com or post your comments to the blog.

I have so many ideas about customize security systems that can be built on your own and at very law cost.
