At SIGNAL we launched Twilio Programmable Wireless which allows you to add cellular data to your IoT projects using a Twilio SIM card. The LinkIt ONE dev board in the SIGNAL hackpack is a perfect place to try out these new capabilities. In the next 5 minutes you’ll learn how to use the cellular functionality of this device using your Twilio SIM card. What You’ll Need Before we get to… Read More

Getting Started with Arduino on the LinkIt ONE

LinkIt ONE

Arduino is an amazing platform for building interactive hardware projects. In the next ten minutes we’ll get our first program running on the SeeedStudio LinkIt ONE development board. If you’re coming to SIGNAL (you are coming to SIGNAL right? – use promo code BSCHOOLEY20 for 20% off your ticket) you’ll be receiving a LinkIt ONE in the Hackpack we’re giving to every attendee. Stop by the… Read More

I hate voicemail. That’s why I text my friends. Sorry, I should elaborate. I mean I text a Twilio number that interfaces with Arduino to translate my text message into morse code which is then tapped out by an old telegraph. Is my means of communication uncommon? Yes. Is it pretty rad? Yes. Am I abusing sarcastic rhetorical questions? Most definitely. Noam Zomerfeld, a design student… Read More

Signal is almost upon us. That means that in just a few days we’ll be handing out hackpacks to every attendee of the conference. The hackpack contains a littleBits-powered Adafruit NeoPixel 8×8 LED Panel that can be programmed to display whatever you can fit onto its display. If you haven’t already read it, check out our recent post detailing what hardware is in the hackpack and… Read More

How to Send SMS And MMS From Your Arduino Yun

arduino-yun-pins-2

The Arduino Yun has built-in WiFi and a second microprocessor which runs Linux. That means that you can write programs in your favorite scripting language and interact with APIs directly from your Arduino. In this tutorial, we’ll learn how to send SMS and MMS from our Arduino Yun using Python and Twilio. By the end we will: Install pip and the Twilio Python helper library on… Read More

TaskRouter and the Internet of Things

The King of Cool

There are millions of devices hooked up to the Internet and generating data, from refrigerators monitoring their contents to webcams tracking intruders. These connected devices, collectively referred to as the “Internet of Things” often create work that needs to be done by humans. How do we keep track of all that work? How do we assign that work to an appropriately skilled and available worker? How… Read More

Build a Photobooth with an Arduino Yun, a Webcam and Dropbox

arduino-yun

The Arduino Yun is an Arduino with built-in WiFi and Linux. With the Yun, not only can you do all the hardware hacking that you’d expect from an Arduino, but you can also connect it to the Internet and run programs in your favorite scripting language. In this tutorial, we’re going to build a proof-of-concept for an Arduino powered photo booth to serve as the foundation… Read More
