Yaler - a simple, open and scalable relay infrastructure IOIO for Android Replacement:DEV-11343. IOIO-OTG is here! Now you can use the IOIO with your Android device or PC! The IOIO (pronounced "yo-yo") is a board specially designed to work with your Android 1.5 and later device. The IOIO board contains a single MCU that acts as a USB host and interprets commands from an Android app. The IOIO acts as a USB host and connects to most Android devices that have USB slave (device) capability. We're now shipping the IOIO board loaded with the V3.04 bootloader so that it's ready to go with the latest application update, which adds Open-Accessory support. We have a blog post that shows or has links to many well documented example projects, with source code. Note: This product is a collaboration with Ytai Ben-Tsvi. Replaces:DEV-10585
emonTx A low power wireless energy monitoring node. It's designed to sense data from multiple CT current sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. It can be powered by 2 x AA batteries or 5V USB. Features and hardware details. The emonTx is based on the Atmega328 8-bit micro-controller and is fully compatible with Arduino IDE. The design is based on the JeeNode. Illustrated Port Map: See emonTx Reference Section for more port mapping info: Thank you to Robert Wall for this diagram. Build an emonTx (kits available in the Shop) Pictorial step-by-step assembly guide New open-source enclosure design on Thingiverse Software All emonTx V2 Arduino Firmware is available on Github: emonTx V2 Arduino Firmware Guide Start by setting up the Arduino programming environment so that your all ready to upload code once you have build the board: Setup the Arduino Programming environment
Paraimpu - The Web of Things is more than Things in the Web 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. If you do, please share your photos with us, we would love to see them ;) There is no USB direct connection, so to program the paperduino you will need some kind of FTDI cable or adapter.

If you raise fish, this and a ph sensor are two important things to monitor (and of course, temperature), and an Arduino is the ideal platform to build upon. The Sensorex DO1200 ($139) outputs a <1mv - 54 mv signal indicating DO levels. Use analogReference(INTERNAL1V1); //Mega & Mega 2560 or analogReference(INTERNAL); //328p based to set the top of the input range to 1.1v. Connect it to one of your analog pins. So: //GND(black original cable) //A3(red original cable) int analogPin = 3; // sensor+ connected to analog pin 3 int val = 0; // variable to store the value read void setup() { Serial.begin(9600); // setup serial analogReference(INTERNAL1V1); //MEGA 2560 } void loop() { val = analogRead(analogPin); // read the input pin Serial.println(val); // debug value delay(500); }
What Is Sanguino? - Sanguino.cc OpenMicros - List of cloud providers Having 'things' on the Internet Of Things isn't much use if there's nowhere on the internet for the things to talk. Luckily, there are several providers that cater for this need. They all have their own way of doing things, and the range from free 'upload your readings here' for they hobbyist, up to fully managed machine to machine (M2M) solutions for even the largest of businesses. What provider is right for you depends on your needs, expectations and wallet. We've carried out some tentative research that might help to narrow down your choice. If you use our products with a cloud provider, we would love to hear about your experiences, good or bad.
