Getting started with Arduino

What is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software.   Arduino boards   are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the   Arduino programming language  (based on  Wiring ), and   the Arduino Software (IDE) , based on  Processing . Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of  accessible knowledge  that can be of great help to novices and experts alike.

Tutorial-3 Ultrasonic sensor Interfacing with Arduino In Advance level

Image
Introduction :       SONAR basically stands for Sound Navigation and Ranging. Ultrasonic is mostly used for the distance measurement prototype applications. It can also be used for measuring the depth of the sea. Ultrasonic/SONAR sensor is an electronic device used to estimate the distance of an object by continuously transmitting sound waves at a particular frequency and listens to that transmitted sound wave to bounce back. It measures the time between the transmission and receiving of that sound wave, which is actually equal to the distance of an object from the SONAR. An optical sensor has both a transmitter to transmit and a receiver to receive the waves. But in comparison to that optical sensor ultrasonic sensor has only a single element for both transmitting and receiving ultrasonic/sound waves. Here i share ultrasonic sensor interfacing and its advance level applications designing like street light controller, vehicle parking systems. Table of Conte
