We live in an exciting time where more and more everyday items “things” are becoming smart! “Things” have sensors and can communicate to other “things” and can provide control to more “things”. The Internet of Things, IoT, is upon us in a huge way and people are rapidly inventing new gadgets that enhance our lives. The price of microcontrollers with the ability to talk over a network keeps dropping and developers can now tinker and build things inexpensively. Continue reading IOT based home automation project

Arduino Based Underground Cable Fault Detection
Introduction
The objective of this project is to determine the distance of underground cable fault from base station in kilometers using an Arduino board. The underground cabling system is a common practice followed in many urban areas. There are many electrical, telephone and other signal cables are laid underground. Continue reading Arduino Based Underground Cable Fault Detection
Matrix Keypad Interfacing with Arduino
The keyboard matrix is the arrangement of circuit connections between the keyboard controller and all the keys on the keyboard. Each key does not have its own dedicated circuit; instead, each key is placed at the intersection of a matrix row and a matrix column. The keyboard repeatedly applies current to each column in turn, and checks to see which rows output current. From this, the keyboard can deduce which keys in that column have been depressed. The matrix takes the form of a printed circuit, either on a conventional PCB, or on membrane sheets. Continue reading Matrix Keypad Interfacing with Arduino
16×2 LCD Display interface with Arduino
Introduction
In this tutorial we will learn How to interface 16×2 LCD display using Arduino UNO. LCD displays available in various sizes 8×1, 16×1, 16×2, 16×4, 20 Char x 4 Lines. These all displays can be interfaced using this tutorial. We are more focusing on 16×2 LCD. It is commonly used.
Sound Level Measurement using Arduino
Sound Level Measurement
Using sound sensor we detect ambient sound. This board along with the microphone, has a small built-in amplifier (integrated circuit LM386), because only the microphone would not be able to send signal to Arduino. The connection scheme is very clean, composed of only 3 pins: Vcc, GND and S (signal). In the middle of the plate, there is a potentiometer for sensitivity adjustment.
