Virtual reality applicationsVirtual Reality is a technology which makes use of software to generate a three-dimensional environment allowing access to life-size objects. It is one of the trending technologies that has gained a lot of attention lately and is being regarded as a revolutionary concept in the technology world. As per a recent report by a website, virtual reality will replace high street shopping by 2050, where users will use VR headsets to try on their clothes and indulge in the atmosphere of a simulated store.

Remote Controlling DC Motor using RF Module (Part - 9/12)

DC Motor controlled using RF ModuleDC Motors are commonly used in electronics and electrical projects. It may be a line-following robot, a remote-controlled car, electronic shutters and doors, digital locks, drones and choppers etc, the DC motors are used in a variety of applications. A lot of these applications require remote controlling the operations of the DC motor. Here, controlling the motor refers to switching motor on or off, changing its speed and altering the direction of its rotation. For example, a remote controlled car may require starting moving or halt, increase or decrease acceleration or move forward or backward by controlling the above mentioned factors of the DC motors attached to its wheels.

Loads defined by Led LightsRF Modules are commonly used for transmission of data over small distances. They do not need a line of sight unlike infrared sensors and can transmit data despite of any physical barriers between the transmitter and the receiver. These low band radio communication modules are extremely popular among electronics hobbyists and serious consumer product designers alike. This project is a demonstration of using RF transmission for controlling loads or appliances installed in a remote location. Since RF modules use low band radio frequencies and operate over small distances, this application can be utilized in a home or office environment for remote controlling appliances or electronic gadgets.

RTC Clock with countdownAlarm Clock, Timer and Stopwatch are common time-keeping features. These functions are so frequently used that it is difficult to imagine modern life without a time-keeping application nowadays. Whether it is a scheduled wake up alarm, a stopwatch to track the time one has jogged or a timer and alarm to schedule office tasks, time-keeping is part and parcel of day-to-day life. This is an Arduino project demonstrating a complete time-keeping application. The project is a real-time clock and allows setting alarms, timers and running stopwatch. It also displays real-time weather conditions with temperature and humidity indications as add-ons.

Overcharging protection for Portable devices (Laptop, Mobile, MP3 player etc) using Arduino and RTC DS1307

Arduino, RTC DS1307 preventing overcharge of your deviceMobile overcharging or Laptop overcharging are common problems. People plug in their laptop or mobile for charging overnight which unintentionally leads to overcharging of the device and reducing the battery life. This project allows avoiding overcharging by letting the user set a timer for charging the device. Apart from this home-based application, the project can also be used in industry environment where over-heating of machines has to be avoided by automating the time of their operations.This ideas was suggested by Jaya Prakash.

This project implements this application by switching off a connected device to the circuit according to a user defined timer.

The Flying CarWith airplanes, we could traverse long distances quickly but not taking us exactly where we want to go but to the nearest airport mostly while sharing the ride with other passengers. Cars will take us to a more precise location as long as it is connected by a road, but at a much slower pace. The fusion of these two technologies will get usa hybrid which retains a portionof the positives from both sides, leading to the birth of the “Flying Car”. This technology has been promised to us by the early 21st century, since the early 1950s as seen in various articles and sci-fi movies. Although the idea has been around for a long time, it could not be converted into a tangible product since it was more complicated than that which met the eye.

Flash memoryFlash Memory is a non-volatile form of computer memory that remembers all the information even when the device is switched off. In this, the user can electronically erase or re-program the data as and when required. Although it was introduced for the first time back in 1980s, the usage has witnessed a rapid increase in the last few years. This is because the production of portable and technologically advanced devices has grown enormously and almost all of these devices are fitted with flash memory.

Here we are going to talk about the basic concept of Flash memory along with all the important details like its working, types and life cycle.

rf receiver and transmitterThe communication technology had its debut with wired communication. The wired communication is still popular and used wide-spread for telephony and internet. Though it was soon realized that wired communication has its own limitations. Its installation incurs high cost and the installation becomes more complicated as the system grows. Moreover wired communication was never a suitable medium for many consumer electronics, industrial and military applications. Then, the discovery of electromagnetic waves and their application in communication came as a great advancement for the mankind.

Internet of things is not a new phenomenon anymore. Even amateurs are trying out Arduino to make some pioneering projects with the help of internet. With so much of buzz around, another innovative IoT project named Nucleus is in news, which is a Smart lock built on Arduino Uno and Ethernet shield. Undoubtedly, different types of electronic locks are flooding the market but they are expensive and use fingerprints, RFID card, Keypad as Key.

Universal stepper motor speed controller

Universal Stepper Motor Speed Control ProjectStepper motor is a digital motor. It rotates as per applied pulses. The pulses have to be applied in specific sequence to motor coil terminals. The speed of motor can be varied by varying the frequency of applied pulses. As the frequency is increased the speed is increased and vice versa. Increasing frequency means decreasing time period – delay of applied pulses. So as the time period of pulses is decreased the speed of motor increases and vice versa. The maximum frequency (means minimum time period) at which the pulses should be applied depends upon the maximum RPM of motor.
