Massimo Banzi announced it some minutes ago during his annual “The state of Arduino” presentation at Maker Faire Bay Area: Arduino Yún is the first of a revolutionary family of wifi products combining Arduino with Linux. Yún means “cloud” in chinese language, as the purpose of this board to make it simple to connect to complex web services directly from Arduino. Designed in collaboration with D
This is a wiring diagram that [Soranne] put together when developing a method of programming PIC microcontrollers using an Arduino board. You can see that he takes care of the 12V issue by connecting the Master Clear (MCLR) pin to an external source. This comes with one warning that the Arduino should always be reset just before making that connection. He’s tested this with a 16F628 and is happy t
Arduino 1.0 is now available from the download page. A long time coming, this release brings small but important changes to clean up the Arduino environment and language – as well as adding lots of additional features. Updates to the environment include a new file extension, toolbar icons, and color scheme as well as a progress bar on compilation and upload. The language changes include modificati
Although there are other ways to do this, [Rod] has decided to write up his method of using two Arduinos and the I2C protocol to expand an Arduino’s IO capacity. As seen in the picture above, you’ll sacrifice 2 analog pins, but if you happen to need IO and have an extra Arduino lying around, this could really help. [Rod] also notes that this method could be used with many Arduino’s in parallel if

先日Google IOで発表された Android Open Accessory。みなさん知ってますよね? Android Open Accessoryは、Android端末と外部機器とをUSBで接続するための規格で、今まで電子工作では何かと苦労していた自作機器との接続を容易にしてくれます。 この規格と同時に、デベロッパー向けの開発キット ADK(Android Open Accessory Development Kit)も公開され、参加者には無料で配られたとかで、ほんと羨まし限りです。 しかし、ADKは Arduino MEGAをベースに作られたオープンソースなハードウェアと言うことで、手持ちのArduino Duemilanove 328を使ってADKモドキを作って、その動作を試してみました。 本物のADKの購入はこちら RT-ADK&RT-ADS ADKの解説はAndroid De
When we heard that Google’s open accessory development standard was forthcoming, we were pretty excited. However once we heard that the reference hardware kit was going to cost nearly $400, our thoughts changed to, “Surely you can’t be serious.” Well, Google is dead serious (and we hear they don’t take kindly to being called Shirley either.) With such a ridiculous asking price, it was only a matte
