We built a mini-crawler robot that draws a path behind it to make interesting designs. We chose this design for a variety of reasons. First and foremost, we experimented with attaching our other materials to the motors, and most of them were too heavy for the motors to handle. In particular, we wanted to use […]
Projects
Mobile Phone Controlled Robot Car using G-Sensor and Arduino
In this article, we are going to Control the Robot Car through the G sensor of our mobile phone and you will be able to move the Robot just by tilting the Phone. We will also use Arduino and RemoteXY app for this G-Sensor Controlled Robot. RemoteXY app is used to create the interface in […]
Interfacing MQ2 to Arduino- Gas Sensor for Smoke-Butane-CH4 and LPG
In this article, we are going to learn how to interface MQ2 Gas Sensor with Arduino. MQ2 is basically a general purpose gas sensor (similar to MQ5) which can sense a broad range of gases like LPG, Butane, Methane(CH4), Hydrogen and in addition to these gases MQ2 is sensitive to smoke as well. In a […]
Interfacing PIR Sensor to Arduino – Connect Motion Sensor/Detector to Arduino
In this article, we are going to learn how to interface/connect PIR Sensor or Passive Infrared Sensor to Arduino. We have written a tutorial on how to interface PIR sensor to 8051 previously in CircuitsToday! So a PIR sensor which is also known as Pyroelectric sensor or Passive Infrared Sensor is basically an electronic sensor […]
Arduino and 7 Segment Display – Interfacing Tutorial
In this article, we are publishing a tutorial on how to interface seven segment LED display to Arduino. Seven segment displays are used in many embedded system and industrial applications where the range of outputs to be shown is known beforehand. Basic 1 digit seven segment display can show numbers from 0-9 and a few characters. […]
LM35 and Arduino – Temperature Measurement and Display on LCD
In this article, we are presenting a tutorial on how to interface LM35 and Arduino along with its program. Once we successfully interface arduino and lm35, we will go on to build a temperature display using arduino and a 16×2 LCD module which constantly monitors temperature around the measurement field/range of LM35 and displays the […]
Interfacing 8×8 LED Matrix with Arduino
LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display a few characters in it. 8×8 matrix consists of 64 dots or pixels. There […]
How to Make an LED Scrollbar
In this tutorial, we are going to build an LED Scroll Bar as shown in the image given below. The project is designed to flash Ten LED strips ( by giving different lighting patterns for each strip) with the help of a control board. We have created a simple GIF animation of the project to […]
Interfacing MQ5 LPG Sensor to Arduino
In this guide, we learn how to interface MQ5 Gas sensor (which is a generic Gas Sensor more suited to detect and determine LPG concentrations) with Arduino. In this tutorial, we are using the MQ5 Gas sensor module (which is widely available in market) . This module has two output possibilities – an analog out […]
Tachometer using arduino
Tachometer is a device used for measuring the number of revolutions of an object in a given interval of time. Usually it is expressed in revolutions per minute or RPM. Earlier tachometers purely mechanical where the revolution is transferred to the tachometer through mechanical coupling (cable or shaft) , the rpm is determined using a […]
