A line follower robot using 8051 microcontroller is already published here and this time the same thing is done using arduino. This line follower robot is basically designed to follow a black line on a white surface. Any way the same project can be used to follow the opposite configuration with appropriate changes in the software. The entire hardware of this simple line follower robot using arduino can be divided into three parts. The sensor, arduino board and the motor driver circuit. Lets have a look at the sensor first. Sensor. The sensor consists of two LED/LDR pairs with appropriate…

This article is another step forward in learning more about Arduino. In our previous article, I have written in detail about blinking an LED using Arduino. We have demonstrated 5 simple led based projects using arduino, which will help you to learn its basic concepts. 1. Blinking Two LED’s using arduino 2. Control LED using a Push button switch 3. Toggle an LED using Push button switch 4. Toggle 2 LED’s using a Push button switch 1. Blinking Two LED’s using Arduino As a beginner, if you have tried the “Hello World” program to blink an LED using Arduino;…

When we learn a new programming language in computer science (say C, PHP or Java), we begin the learning curve with the classic “Hello World” program. We learn some essential keywords used in the programming language, then we learn the structure of the language and finally we begin to play with the language by making it display the two words “hello world” in our computer screen. So that’s how we begin to learn a programming language used to build computer applications. Our world of embedded systems is a little different. We create software to control hardware. In our world, we…

It was in the year 2005 that the first ever Arduino board was born in the classrooms of the Interactive Design Institute in Ivrea, Italy. Well, if you are not very familiar with the term, an Arduino is an Open Source microcontroller based development board that has opened the doors of electronics to a number of designers and creative engineers. It was in the Interactive Design Institute that a hardware thesis was contributed for a wiring design by a Colombian student named Hernando Barragan. The title of the thesis was “Arduino–La rivoluzione dell’open hardware” (“Arduino – The Revolution of Open…

In this article, we explain the basics surrounding arduino. As the title indicates, this article is for absolute beginners in the world of electronics and for people who are beginning with arduino boards. Arduino is an electronics prototyping platform based on a micro controller. Arduino boards are usually made using Atmel’s Atmega series micro controllers or ARM micro controllers. Arduino is an open source hardware project which means the designs of board (the hardware architecture, CAD files) are available to public with open source license. Anyone can modify the hardware designs and the associated software. What you can do with…

Arduino has now become a strong platform for creating and developing various open-source hobbyist electronic projects. Its relative ease of use, versatility, and the unbeatable price have all made Arduino into the prototyping board of choice for many home-brew electronic enthusiasts worldwide. In this article, we review 4 of the best arduino project books available till date. We have already listed 4 books to learn the basics of Arduino. If you are looking out for a practical and a little more advanced approach to Arduino we suggest you to read any or all of the books we have reviewed below…

In this article, we provide you review of 3 popular books that can provide you good knowledge in Arduino platform. These books give all the basics needed in electronics as well as programming. Simple as well as complicated projects are also provided with detailed explanation and codes so that the reader can get some application level skills as well. These books are ideal for the novice as well as expert in electronics, who would like to begin playing with Arduino. #1 Beginning Arduino – Michael McRoberts Beginning Arduino by Michael McRoberts This is considered one of the best arduino books…

Ever thought of working with microcontrollers, but resisted due to lack of knowledge about them? Ever made a futile attempt of reading a whole microcontroller datasheet? Ever found hard learning (memorizing) the assembly syntax and keywords? Can’t afford to buy the costly USB programmers for your microcontrollers? Get ready.! Arduino answers your laments! What is Arduino?: Well, first let me explain what arduino exactly is. Arduino in general is a opensource platform targetting hobbiysts. Most of us using the interent would have came across the word “opensouce”. Opensource is a methodology where, the developers of a software/hardware give the end user…
