Abstract RADAR is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. Radar systems come in a variety of sizes and have different performance specifications. Some radar systems are used for air-traffic control at airports, and others are used for long range surveillance and early-warning systems. A […]

Story We love our workshop, but it has one downside (or maybe upside) – a large flight of stairs to the gallery. We constantly need to move parts and components between one floor and the other, so we’ve been plotting different ideas: drones, dogs, carrier pigeons and what not, and then it hit us! A

We all are familiar with dice and often played LUDO or SANP SIDI (Snake & Ladders) game by using dice. Dice is a squire type solid box which contains 6 different numbers on all of its sides. We throw dice on a surface to get a random number while playing the games. In this project

You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after sometime. A number of technologies are available to make such kinds of systems like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this arduino based project, we have
Automatic Door Opener using Arduino Continue Reading
After designing this line follower robot using arduino uno, I have developed this computer controlled robot. It can be controlled via the computer and we can use specific keyboard keys to move it. It runs over serial communication which we have already discussed in our previous project – PC Controlled Home Automation. Components Required Arduino UNO DC

In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. We are here with our next robot that is Mobile or DTMF Controlled Robot. DTMF controlled Robot

Here we are going to interface a DC motor to Arduino UNO and its speed is controlled. This is done by PWM (Pulse Width Modulation). This feature is enabled in UNO to get variable voltage over constant voltage. The method of PWM is explained here; consider a simple circuit as shown in figure. If the

This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below. Now if the switch in the figure is closed continuously over

In this Arduino based project, we are going to control DC fan speed according to the room temperature and show these parameter changes on a 16×2 LCD display. It is accomplished by the data communications between Arduino, LCD, DHT11 sensor Module and DC fan that is controlled by using PWM. PWM is a technique by
Arduino Temperature Control – Adjust Fan Speed based on Temperature Continue Reading
To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units – big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays
