Looking for a MINI project to submit in school or college? Then this may be perfect for you! Built using ATmega8 microcontroller that is accepted in most university of India. Much more advance than a 8051 MCU. Project is complete with full project report ready to be submitted!

Project Abstract

This device can be used to code protect any electrical device (like an electronic door, lock or safe). The user must enter a correct password to gain access. The password is entered using the built in 44 keypad matrix. The main LCD Module is used to display messages to the user. As soon as correct password is entered the relay is activated. This is indicated by a LED which is placed near the relay. The relay remains on as long as the user wishes. You just need to press a key to deactivate the relay.

After typing four digit password you must press the "OK" button (S8). At anytime you may press the "Cancel" key (S12 )to clear the input (e.g. when you enter any incorrect digit)

The smart code lock has the feature to change the password too. For this enter a special password which is 0000′, as soon as the system receives this special password it switches to change password mode. Here you need to enter the old password to gain permission, then enter the new password.

The smart code lock also support power saving feature. The backlight of LCD turns off automatically when the system is idle for few seconds. The cool thing about this is that it uses PWM to control the brightness of LCD Backlight. So the dimming is very smooth and it is like those used in many mobile phones.

This is the complete DIY Kit for AVR Based Smart Code Lock Project. Nice for learning microcontroller programming by actually making a working project. Our projects are highly documented and easy to make. The KIT includes a pre-programmed microcontroller, PCB and all parts. Detailed build instructions and firmware available here at

* Engineering & Maintenance charges the time and effort required to realize the project. It basically includes the charges paid to the engineers and designers who conceptualize the project, makes schematics and PCB layouts, write and debug programs, finally makes the project usable by providing documentation which includes writing knowledge base articles, taking photographs, making extensive graphics etc. The charge also includes the hosting cost of the project and relevant files on the server.

    Great project. Working perfect. Wonder if we can interface a membrane keypad instead of buttons.
