Features include the ability to have the Arduino send an SMS message when a sensor or data set reaches a specific threshold, or even send and receive voice calls directly to your Arduino based ...

They used the webaudio API to send serial data to a remote Arduino. The hack uses a FET, a capacitor, and a few resistors. They didn’t quite build a real modem with the audio.

I like to visualize things, so I decided to prepare this simple tutorial to help you better understand how to visualize data using Arduino. This tutorial assumes that you have some basic electronics ...

How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task.

Particle’s Electron is a “cellular Arduino” with a global data plan ARM- and GSM-based board promises quick on-ramp for mobile IoT development.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

[Ido Gendel] was thinking about new and interesting ways to send data between devices, when he realized that the answer was right in his hand. Literally: he decided to try sending data using the mo… ...
