Using a webcam and a Raspberry Pi device, we built a car counter and aimed it at a busy highway. We deployed a car-counting algorithm to the Raspberry Pi and used ThingSpeak and MATLAB to analyze and visualize the traffic patterns.
We built our own Arduino-based weather station and hooked it to ThingSpeak to collect and store weather data. One year later, we share how to deal with bad data and how to analyze and visualize data using ThingSpeak and MATLAB.
Getting your boat stuck in a shallow bay is easy if you do not know how deep the water is. Accurate tide predictions and real-time water levels are not available for most bays and estuaries, but you can build your own low-cost, real-time tweeting tide gauge.
The CheerLights project demonstrates a way to connect physical things through social networking. People around the world synchronize lights to the same color set by Twitter. Anyone can change the color. Go ahead—spread some cheer!
