Over the years, demand for efficient, light, fast-charging, safe, and cost-effective portable power has led to development of many new battery technologies, including nickel-metal hydride (NiMH), rechargeable alkaline, lithium-ion (Li-ion), and lithium-polymer (Li-poly), to name a few. Generally speaking, these new battery chemistries require more sophisticated charging and protection circuitry to maximize performance and ensure […]

This electronic instrument allows you to sequence and loop audio and MIDI data.  Most of the time I use it to sequence drum samples so I can play around with different beats and rhythms.  The really great thing about this instrument is that it is very portable, it fits in your hands easily, runs off […]

this is a project which makes an android app, then configure it to use it with android debug bridge or android accessory development kit. for making the android app we use android mode of processing. For hardware, I always choose Arduino. Here I have a Freeduino ADK from embedded market. for the communication since ADK […]

Intel may have grabbed the headlines with the announcement that its first 14nm processor will be on general release next year. But by then the Broadwell processor will just one of a number of 14nm chips in production. Intel has long insisted that its production capability, which it has always invested in to keep at […]

I’m working on an Arduino clone.  The Arduino is essentially an ATMEGA328P development board with a bootloader pre-loaded.  There are a lot of custom macros built into the programming interface that make it really easy to use, and even easy to build some powerful applications.  Arduinos have taken off and can be found everywhere, doing […]

I have loved making projects with Arduinos, but at $30 a piece your projects can get expensive. So I want to show you how you can make your own Arduino from scratch and save money doing it. Make your own Arduino for around $8. For this instructable I show you how to make one on […]

The Freetronics LeoStick is a handy break-out board for the ATmega32U4 microcontroller. The board has a convenient USB stick format, and is based on the pinout and connections of the Arduino Leonardo reference design for compatibility with the Arduino IDE. Before you plug in your LeoStick for the first time please read this section of the […]

So, I have always wanted a nice lamp by the side of my bed, Something simple with out any buttons. Of course this would mean it had to be wireless. I also wanted to use it from my bed but not getting out of my bed to turn it off. So it had to be remote controlled, […]

Tyree (he wears a tie and he has tires) actually smiles after he bumps into something (see video). Using an Arduino motor shield, he detects obstacles using the “more current into the motor means something is in the way” principle. Tyree started out as a sketch and morphed into a real object thanks to Autodesk’s […]

In this article we are going to take a detailed look at how to build the driving circuit for the 8x8x8 LED cube. In other words we are going to design and analyze the circuit which translates the signals coming from the Arduino to appropriate currents passing through each of the LEDs, so that the […]
