Register now for the Hands-on Workshop at DEVintersection in Orlando, Florida. Use discount code SEVEN April 18, 206 – Walt Disney World Swan Resort  The Internet of Things (IoT) is the latest in an ever growing realm of technology that modern developers have to know about. To get into the IoT you have to […]

IoT Workshop


Welcome to the World of IoT  

Building the Internet of Things with Doug Seven


Richard Campbell from DEVintersection chats with Doug Seven about his IoT workshops, engaging with developers to see just how small computers can be made now, and how you can create a network of ultra-small devices to work together to provide a huge amount of data about the world around you. Using development tools, languages and […]

Using Particle Photon with Johnny Five and VoodooSpark


I am elbow deep preparing an updated IoT workshop for three conferences in the next two months: TECHintersection – September 14, 2015 in Montery, CA DEVintersection Europe – October 17, 2015 in Amsterdam, Netherlands DEVintersection – October 29, 2015 in Las Vegas, NV For these workshops I’ve decided to do something different – mostly driven […]

TECHintersection-IoT Speaker Profile: Zach Supalla,


The TECHintersection event is coming up on September 14th through the 17th. I have been helping with the planning, specifically around the Internet of Things (IoT) content. As we lead up to the event I want to familiarize you with some of the great speakers we will have. This is going to be a great […]

Another IoT Workshop Scheduled


If you saw this post you know that the last IoT Workshop my team and I hosted was a blast. We are getting ready to add some new labs to in preparation for another workshop event on Monday, September 14th. If you missed the last one, you should definitely come to this one – […]

IoT Labs @


Over the past few week my team and I have been working on a set of self-paced labs for building Internet connected Things using Arduino. Last night we got together with 150 of our closest DevIntersection/anglebrackets friends and had a great hack event. Lots of developers got their first exposure to Arduino and to building […]

IoT Workshop: Lesson 3 – Input Controls Output


In this lesson you will combine the ideas that you learned in the previous lessons (here and here) to make a LED change its brightness based on the level of light available – essentially a nightlight. You will learn a couple of new methods you can use and we’ll discuss Pulse Wave Modulation (PWM) briefly. […]

Arduino: Reading Analog Voltage

ReadAnalogVoltage Sketch

In this lesson you will use two resistors – a static resistor and a variable resistor – to create a voltage divider that enables you to effectively understand the intensity of light detected by the photoresistor – essentially a light meter. In the previous lesson you learned how to send OUTPUT and in this lesson […]

Arduino ‘Hello, World!’ – Sending Digital Output

Blinky Sketch

I just posted my first lesson to This is the first in a series of IoT lessons using the Arduino Yun. The lessons will build from this ‘Hello, World!’ lesson to fully connected devices leveraging Cloud IoT services, web and mobile apps, and backend analytics and machine learning. Check out lesson #1 here.
