So this app has some basic features in it today, that can be found in multiple free apps or put together in other paid apps. This one does a great job of bringing them together nicely. I like the ability to store/search datasheets in the application. that is handy! Everything i've gotten from adafruit (hardware and this software) has been good quality and well maintained. Keep up the good work lady ada and crew!

Non-Lexical Vocables Photo The real world can be a harsh environment for your project when it's ready to leave the work bench. Circuits with an external power supply, whether it's batteries, the 12-volt supply in a vehicle or an AC-DC converter, can be exposed to reversed polarity or voltages outside the expected range. Many of us have made the mistake of reversing power supply polarity with usually fatal consequences.

The Internet of Things , a term being bandied to the point of almost meaninglessness now it’s hit the mainstream of the NYT and the BBC . Yet, while the mainstay of the media struggles to describe how and why smart sensor arrays are going to mean you spend less time in traffic, ultimately pay more for your electricity but make sure your fruit is always fresh, there is a quiet revolution taking place. The action taking place is the creation of what I call the Sensor Commons. Why is this a revolution? Because as a population we are deciding that governments and civic planners no longer have the ability to provide meaningful information at a local level.

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring ) and the Arduino development environment (based on Processing ). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g.
Hack a Day
This circuit is how [John Tsiombikas] makes his cheap 3D shutter glasses work with a Linux machine . It’s not that they were incompatible with Linux. The issue is that only certain video cards have the stereo port necessary to drive the head-mounted hardware. Shutter glasses block light from one eye at a time, so that different renderings can be shown to create the stereoscopic effect. Since stimulating the muscles in the eye doesn’t actually work , you need to find a way to drive the glasses in perfect time with the video signal.

Were you ever the kind of person to hack up your own Playstation controllers and hook it up to something else? Well, those shards of plastic can be mighty dangerous, so I’ve done it for you. And hey, with the GamePack you’ll even have something you can hook it up to. The GamePack comes with an Arduino, MeCap Backpack, TouchShield Stealth or Slide, ExtenderShield and an InputShield- everything you need to create your own open source, portable gaming device.

TinkerKit simplifies electronic prototyping throughout a wide variety of sensors and actuators mounted on orange-coloured boards that you can hook up to the Arduino through the Sensor Shield. Each module uses the same 3-pin cables that can't be plugged the wrong way around. A small signal amplifier helps to stabilize the signals running on the cables, ensuring reliable transmission from the sensors even on long distances (1m-5m).
About Fritzing Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics. We are creating a software and website in the spirit of Processing and Arduino , developing a tool that allows users to document their prototypes, share them with others, teach electronics in a classroom, and to create a pcb layout for professional manufacturing . Just got into interactive electronics and still need the basic tools? We created an "all-you-need-to-get-going" Fritzing Starter Kit .

Kerry D. Wong » Blog Archive » A Sensitive DIY Ultrasonic Range Sensor
I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself? The theory behind ultrasonic ranging is quite simple. Typically a short ultrasonic burst is transmitted from the transmitter.Project – Simple RFID access system - Birds on the Wire
Hello Readers The purpose of this project is to prototype a basic RFID access system. Although it is not that complicated, this article is my response to a kit reviewed in the Australian “Silicon Chip” (November 2010) electronics magazine.Kinect Hacks | Connect with Kinect Hacks!
People are really starting to do some life changing work using the Microsoft Kinect sensor. Take for example this latest team of developers and their viSparsh belt for the blind . The apparatus comes equipped with a kinect sensor that sends proximity data to devices embedded into the belt which trigger vibrations when approaching objects. It's a brilliant idea that will help the millions of people who suffer from sight related problems. Couple this device with a cane and you'll be providing a great service to those less fortunate.I’m working on an I2C project, but I don’t have a sampling oscilloscope and I need to see what the heck is going on, so I put together this quick and dirty I2C sniffer sketch. You connect two digital pins on the Arduino to the I2C bus lines SDA and SCL, and Arduino ground to I2C ground. The digital pins on the Arduino must be on PORTD, which are pins 0 through 7. It’s probably a good idea to avoid the serial lines, which means you should use any two pins between 2 and 7.
