“Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s inteded for artists, designers, hobbysists and anyone interested in creatibf interactive objects or environment.” – Arduino Official Website

Indeed Arduino has revolutionized the concept of prototyping and rapid development. It only takes an idea and concept to start working with Arduino. Internet is flooded with tons of information related to Arduino and its Shields. In this article you will be shown how to get started with Arduino UNO and run you first program. Continue reading

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It’s an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.
Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Continue reading

Electronics: How to interpret semiconductor devices model numbers.

Post Thumbnail of Electronics: How to interpret semiconductor devices model numbers.

The post states the formats used for numbering the transistors, diodes and other semiconductor devices. It will make easy to identify the device by its model number. We have been using so many semiconductor devices and most of the times don’t know what there serial numbers really mean. Mainly there are 2 numbering standards used;

European based Pro-Electron System (for eg 1N4001, 2N2222)
American based JEDEC System (BC546, BC547) Continue reading

This post describes how you can connect a real-world device with virtual-world of Proteus. The usage possibilities are unlimites and hence it breaks the unwanted-barrier between Proteus and Real World. COM Port Physical Interface Model which enables the “physical” serial port of your PC to available to simulation within Proteus. With it you can connect any of the “virtual” component found in Proteus with your PC Serial port. In other word this model connects your physical world with the Proteus-Virtual-World :) Continue reading

Long exposure light-drawing or “light-painting photography has become pretty popular lately. We see images pop up all the time that look pretty cool. Most of the time people do it by lights in their hand and setup camera onto long exposure. But this project shows what happens if an engineer gets into light-painting. Nils Völker wasn’t feeling very artistic so he made himself a robot. With light at is top the robots makes pattern which are captured on long-exposure. Of course the patterns are pre-defined which can be changed through programming. Continue reading

News: NEC Builds Battery-less Remote Control

 Technology         View Comments

How often do you change the batteries in your television remote control? Yeah, basically never. But that’s a tribute to how efficient the device is and not a reason to overlook this development. NEC is showing off a remote control that uses no batteries. Power is generated using the piezo effect that occurs when a button is pushed. That is to say, when a crystal is compressed it emits a tiny bit of electricity which is harnessed and used to power this device. This is the same principle that is used in the electricity producing sidewalks tested in Japan.

It’s pretty phenomenal that they can run the device using this method. Right now there’s only a handful of buttons but we’re sure there’ll be advances in the technology. There’s a ton of use for this if it can be miniaturized. It is using radio frequency instead of infrared, making it a useful development in wireless doorbells, garage door openers, key-less entry fobs for your car, and many more applications.
