Sound / / Piezos diagram: Inside the Piezo Buzzer A Piezo is an electronic device that can be used to play tones and to detect tones. The normal piezoelectric effect is generating electricity from squeezing a crystal. RFduino much more than just a tiny computer with Bluetooth 4.0 - EP&Dee With the RFduino, the Arduino open-source platform is now able to offer a wireless alternative. The wireless-enabled microcontroller is scarcely the size of a fingertip and communicates with smartphones, tablets and laptops which have a Bluetooth SMART READY logo. Using RFduino, developers are able to build a system in just a few minutes which transfers data from sensors to a laptop or other Bluetooth-enabled devices. They can also use a smartphone to control the peripherals connected to the RFduino. Rutronik also offers identical modules and chips for mass production, depending on project requirements.

10 Great Intel Galileo Features Intel and Arduino’s announcement about the new Galileo board is big news. It’s a Linux-based board that I’ve found to be remarkably compatible with the Arduino ecosystem based on my first few steps with a prerelease version of the board. Here are some of the best features of this groundbreaking collaboration between Intel and Arduino: Shield Compatibility The expansion header on the top of Galileo should look familiar since it’s compatible with 5V and 3.3V Arduino shields designed for the Uno R3 (also known as the Arduino 1.0 pinout). Blog » robot In conjunction with the release of the new version of the Arduino IDE and the Arduino Robot, we’re also putting out a TCT LCD screen. The screen was developed in conjunction with Complubot and the library relies on the Adafruit GFX and ST7735 libraries. The screen lets you do all sorts of fun things, like play games or lose the serial monitor to see the values from sensors.

Tutorial Series for Arduino: It begins. This video was featured on the Adafruit Blog on 01/06/11 This tutorial was featured on the official Arduino blog on 3/9/2011 This video was featured on the DIYFilm Blog on 03/19/11 Thanks to a generous sponsorship from element14, I’m putting together a tutorial series on using the arduino microcontroller platform! The arduino is a platform that I’ve done several projects with, and I think it is the best possible way for beginners to get acquainted with electronics. This tutorial series will be aimed at beginner users, but I’m hoping to keep it going with some more advanced topics a few episodes into the future. This first episode will get you acquainted with the arduino uno (the current “flagship” arduino), introduce the programming language, and help you get your first program running! You can download the files associated with this episode here:

Arduino + Servo + openCV Tutorial [#openFrameworks] by Joshua Noble One of the my favorite things about has always been the small tags one can find beneath the name of an application indicating among other things, the technology used to create it. That little nod to the process and to all the work that went into creating the libraries and techniques that an artist or designer uses helps not only contextualize the work but it also helps give recognition to everyone who has contributed their time and expertise to building tools for creative expression in code. Figuring that some of the readers might be interested in learning a little more about these frameworks I’ve put together a quick walk-through of how to connect up two of those tools that one so often sees attached to the names of the projects profiled here: openFrameworks and Arduino. Arduino For this tutorial you’ll need a few things: 1 x Arduino-compatible device 1 x Trossen Servokit 1 x USB cable 1 x Breadboard and wires to connect the Servos to the Arduino

RFduino by RFDigital Cortex™ ARM® M0256kB Flash2, 4 GHz TransceiverBluetooth 4.0 Low Energy RUTRONIK offers RFduino system exclusively in Europe to B2B customers. List of Arduino boards and compatible systems This is a non-exhaustive list of Arduino boards and compatible systems. It lists boards in these categories: Released under the official Arduino nameArduino "shield" compatibleDevelopment-environment compatibleBased on non-Atmel processors Where different from the Arduino base feature set, compatibility, features, and licensing details are included. Official Arduino versions[edit] Many versions of the official Arduino hardware have been commercially produced to date:[1][2] Guilherme Martins : PAPERduino’s design This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D This is the the first version of the layout design, next we will try more designs, and another materials. You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards.
