Ultrasonic range finder using arduino

praveen June 19, 2014 7 Comments
Ultrasonic range finder using arduino. Ultrasonic range finder using 8051 mictrocontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment display. This range finder can measure up to 200 cm and has an accuracy of 1cm. There is an option for displaying the distance in inch also. Typical...

0-5V voltmeter using arduino. This article is about a simple 3 digit voltmeter using arduino. The circuit can measure anything between 0 to 5V at an accuracy of 50mV. The circuit uses minimum number of external components and can be easily modified for different voltage ranges. The display device is a common anode multiplexed seven segment LED display module (Type No:E1-3056ASR1). Let’s have a look at the display device first. E1-3056ASR1. It is a low cost multiplexed 3 digit...

Blink LED with Arduino – say Hello World

jojo March 28, 2014 No Comments
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...

Arduino (For beginners)

Anish February 4, 2016 13 Comments
We have developed this article as a beginners guide for Arduino.  We have compiled many of our arduino articles to help you understand the board better and begin your first serious project using Arduino. So let’s begin. 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...
