Arduino-Based Door Lock System

Authors: Adetunji Yinka Clement, Anumbor Ogor

Introduction 

The rate at which theft is growing nowadays is highly alarming. As theft is increasing, security is becoming a major concern, hence the need for embedded security systems such as the presentation in this article. 

In this project, a door lock system with a 4x4 keypad, dc motor and Arduino uno is presented. From the keypad, a password is typed and the door will be opened only if the password is correct. Two indicator  LEDs; a red led and a green led is interfaced with the Arduino, the green LED comes ON if the password is correctly entered and red led is turned ON if wrong password is entered.

Here is a video demonstration of the project:

Arduino-based Seven Segments LED Scrolling Text (Episode 1)

Introduction

The project is a seven segments common anode LED display system based on the Arduino development board which makes strings of texts loaded to the Arduino to scroll across the LEDs segments.
