A Xively logger library for Spark Core

Davide Gironi writes: Xively (formerly Cosm and before that Pachube) is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that data. This library is a modular and configurable Xively data logger, built […]

WiFi globalCALCnet with the Spark Core

A wireless calculator networking with WiFi gCn using the Spark Core.  KermMartian of Cemetech writes: This current project achieves all the goals of that project, and more: it provides a computer-free way to connect calculators to the internet, and lets the calculators independently configure the bridge device as well. The two components that were necessary to […]

Measure audio level using root mean square on Spark Core

Davide Gironi writes: A Spark.io library to retrive RMS and Spl value from an audio input. This library reads data from an ADC pin and returns the RMS value of the input simply using RMS avarage. The root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of […]

Spark Core: Wi-Fi for everything (Arduino compatible)

Spark Core: Wi-Fi for Everything (Arduino Compatible) The Spark Core is an Arduino-compatible, Wi-Fi enabled, cloud-powered development platform that makes creating internet-connected hardware a breeze. This little board packs a punch: with a 72 MHz ARM Cortex M3, the best Wi-Fi module on the market, wireless programming, and lots of pin outs and peripherals, there’s […]
